Refractive index of prism || 11th physics practical #11thphysics @a2zpractical991

Hello friends and welcome to my channel So friends, I am Sachin Shukla and you are watching E2J practical. So, friends, today's practical is basically the 11th physics practical experiment. Experiment Number 9, Reflective Index of Prism So basically, we have to make a graph here; we have to plot the value of IM. So many things we will see in this, and you don't have to go anywhere. Friends, I am uploading all the practicals of chemistry and physics here Basically, I have also uploaded all the chemistry. Go and check out the playlist and take help from it Okay, so let me show you the experiment. In this, we will begin experiment number 9, Refractive Index of Prism. Its aim is to determine the angle of minimum deviation from the given prism. by the graph plotted between the angle of incidence and the angle of deviation So how do you conduct this experiment? Let me show you quickly You are seeing this prism And here you are seeing the line by x and y We have to plot all of this. So how do you conduct this experiment? Let me tell you See one more thing here How much angle of incidence do I need to take? 35, 40, 45, and 50 I'll take only 3 here And we will see what the angle of deviation is for this First we have to take the paper Okay And what do we have to do with this? With the help of a pin I have a pin. We have to use pins on all four sides. So that this paper doesn't move So I What we will do We will draw a line from the middle. We will call this line x and y. After that we basically If this line is 15 15 and how much is this 10 Means 25 I will draw a line of 5 cm here. I'll take one here 5 1 2 3 And here 4 Now what we have to do with the line We have to draw it on the upper side We call it normal. So I will draw a line here Okay I will draw a straight line here 1 4 Okay You have to draw these four lines We call it normal. I will name it. N1 N2 N3 And this will be our N4 Now what you have to do If you want to take an angle I will show you here We already have four angles given. That's what I told you 35, 40, 45, and 50 So first I take 35 How much will I take first? 35-degree angle Friends, now here's what you have to do With the help of the protector You have to keep the protector on this normal. Right in the middle Clear The line that was passed here You have to keep it on this And here you must take the first angle 35 So I pointed out here 35 And what you have to do on the 35th You have to draw this line from here. Okay And where will it come down from here? In the dotted line You have to take it like this In dot form Okay Same You have to do the same for this. Here you must keep the protector. And what is the measure of the second angle? To take 40 So how much will I take here 40 Okay Here I will draw this line at 40 I will draw the line And exactly In the opposite direction What you have to do In the dotted line Like this How much do you need to draw the third one? 45 So I drew this for the third one I drew this for the third one I drew 45 for the third one. So here it will come 45 Here it comes 45 And how much will it cost? In the dotted line How much is this? 35 This is 40 degrees And this is 45 degrees And how much do you have to take the last one? 50 How much do you have to take the last one? 50 So this is 50 I will draw 50 like this And where will it come from? In the dotted line Exactly This is done. Now, friends How much is this? 50 I will write the names of all the lines. Like this This will be R1 This will be R2 This will be R3. And this will be R4 Now what you have to do Friends That you have to Now you have to take this prism. Okay This is 35 What you have to do You have to take the prism You have to keep the prism Exactly in the center You must keep the prism. Exactly in the center You have to keep the prism Exactly in the center As precise as possible Less You have to take it exactly in the center And you have to draw a line from here What you have to do from here You have to draw a line. Okay Same You have to do this for everyone What you have to do Friends You have to take a pin. You must attach it. On this line On the R1 line What you have to do You must attach it. So here is my R1 line I'll put a pin here Okay And I'll place the second pin a little further ahead. These two pins need to be attached to you, okay? What you will now see is that the image of this pin will appear on this eyelid. This eyelash will create the image of this pin on the eyelid. And where this pin image will come on this area, below it you need to place two pins. So if I show you right here, on this eyelash, what's coming in, it's a pin, coming in. Right in front of this pin — this pin Right in front, two pins are stuck in the mud. Then I'll show you by doing it. I've already told you, come inside. What needs to be done with the chronometer? This entire thing. . . Google Bull Share He wants to say everything. You will also receive a vaccination, and you will be given a vaccination certificate. Even there, in one of the printers, something needs to be printed. This point here, you can now write its name as q1, q2, q3, and q4 might be placed here, okay. Now you've got this right here. Now, we need to do the same for the others, so let me quickly measure this one too. I'll place it right here, in the middle. I will place two pins on this again. Two pins can even be placed at ten millimeters. The two pins must be placed perfectly straight. The other pin must be placed exactly opposite to this one. Now I will remove the prisms from here and reinsert one Where did I get the vaccine here? What should I do next? I'll play this match; you can apply it, P. Fi back to You have to keep this one, take it out, and bring it back completely. When it happens, on the large site you see it appearing as a huge image. And just like that, you have to plot it right in front of you. Alright, now we just need to remove this. And back here, the pin you just placed You have to touch both these pants here. One last thing, we'll do that too. Here, take a break Now you just need to attach another pin here, right at Sambang. You must remove this and draw a line here. Now you can give a name to all these points As I will give it a name, here is where it is being attached F1, F2, F3, and how much will this become F4? Its P7, P8, P9, P10 In the video, you need to focus on this, as it's the key angle to highlight. Why is this happening here, and who is doing it? Angle of deviation So if you want to measure the angle of this This one, this one, this one Keep the key, the knife, the ring, and the protector here. How much is the total bill and the angle you're looking at? Philal, my previous one, the one before that, not the 40, not the previous one, the tander, no, no 51 degrees Foot degree Your angle of 35 was the cause of the VAW incident. 40 Cure 40 is coming in. I'll keep it at 40 degrees. What was the angle W deviation for 40? This is our 40, so it was coming for 38. How much was coming for the third 45? It was coming at 45. And for 50, ours You can see us coming. 51 You'll have to do the same below as well, just fill it out So, how long have you been using the angle and prism? It's for four Now we will create a graph Where we people are del What value should we take? Let's take the value. Okay. From the graph You need to draw two lines. x-axis and As for the y-axis, I've done this I am along the x-axis and y-axis Take the coordinates zero zero here. A side, it's x- x- y- Also write these Now what is the value to me What have you got? So, this is from you. I will make a chart here just as I'm taking it here. I'm taking the scale here. So I'm going to take the scale here on the y-axis How much will the deviation be for us today? 1 cm is equal to how much? 5 After that I'll take it along the x-axis here 1 cm is equal to 5 degrees Alright, now I'll plot this, piece by piece. I took 5, I took 10, I took 15 20 25 Then 30 will come. 35 and this 40 45 50 I'll keep it the same way here too 5 10 15 20 25 And this is 30 35 Take it here like this Alright You are given the x-axis and y-axis axes You also need to write what plot you are plotting. Then the angle of deviation will come here And what will come here today? angle of incidence Alright Now I will start drawing lines So, how much is yours right now? First, how much is yours? angle of incidence is 35 You are getting 40 at 35 Then I'll put a tick mark at 35 and 40. It's fine here. The second one is coming to me at 38 out of 40 How much did I get for 40? 38 The third one is coming to me at 45 out of 45 And the fourth one is 50 out of 51 Alright Now I need to get this thing called a bicycle What should the shape of this graph look like? curve shape What shape should the curve have? Alright, let me draw this then. You're looking at a curve. How do I get there from here? So basically, you have to do it like this Drawing will remain. That's the point—this is exactly what will happen to you. Now you have to put it completely below You need to touch it from the x-axis. So this is the bicycle, our bicycle. It is said that a way will emerge from the hardship. So, one, one, one is lying down. So you took three eagles here Alright, fine, fine, things are going well Forty-five and forty-four was Tharifive Forty Proceeded further It's 45. 45 plus 50 sorry 1234 valiyos were there, what were you supposed to do? Deactivate from PooR to 170 Aaa Now fully fiverek sign 0 You will get it once you complete the entire Kalki. 39.75 Alright, you're hot. 21.25 This is our 31.25 You will sign this. A bill will be sent to you for 39.75. 0.8869 And its sign 2 21.25 will be matched. 0.6 You have already made it deviate, AA You will get this 1.47 wide, you can use it If you're going to make a fuss, then do it yourself. This is the same, the fence is low. Davishawn, our heart A few inches past the corner, how much prism do you need if you want to make a very, very good prism? What is your result here?
