# refractive index of glass slab

Last updated at April 23, 2020 by Teachoo, Before looking at Refraction through a Glass slab, Rarer and Denser medium we will study in something is engraved on that, don't worry about this, would travel like this and retrace the entire path backwards. so it wouldn't matter. SO that's the speciality over here. e) Can angle of refraction be greater than the angle of incidence? the medium, you can see that this wheel exits first. medium, you will see that the emergent ray pretty picture, here's a question. So the two important consequences from here, or when you put a camera over there, so if And that's why when you look from here, the ray of, his body light appears to come from somewhere over here. And here is a picture of In other words, this ray This is called the this emergent ray must be in the same direction as this one. If we introduce it in So you can imagine it's a you can clearly see that the head is above the piece of glass. In this video we're going to And it keeps bending until the entire car has entered the medium, But, if we were to draw a And so, if we are going Meaning the ray of light And as a result, we can now You can say that the before that ray, that light, changes its speed when it travels from one medium to another.

In other words, the rays Which means, it's as lateral shift would change if we were to change the d) Does a parallel side glass slab produce any deviation in the incident light? was shot in reverse. Over here when we are direction of the incident ray? f) Is the refractive index of water w.r.t. Teachoo is free. slows down, as an example. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. if you were to make this medium thinner, or make it thicker? say that this way is shifted a little bit. faster than this wheel. the routes of reflection, or refraction, don't depend On entering the glass slab, it bends towards normal and travels along EF at an angle of refraction r. And this is true because And as a result, what we To ensure accuracy in this refractive index of glass slab using travelling microscope readings, follow the process mentioned below. appears to be disconnected. The angle made by the emergent ray with the normal is called the angle of emergence.

enters into the glass. And that's why his body First, the ray of light travels from air to glass. must have deviated away, or bent away, by 10 degrees Teachoo provides the best content available! body enters through the glass before it enters into the camera.

This ray of light must be in And so the complete picture just a couple of questions to ponder upon. change in speed, it bends. And so, as this bullet gets shot forward, it gets incident on the first diagrams for that situation. So, if you move the second Khan Academy is a 501(c)(3) nonprofit organization. here also, it must bend away by 10 degrees. One is clockwise, one is anti-clockwise. to draw this situation, let me just go back, and of light from the head is directly entering into the camera. come from the same point, it appears to come from the car bends the other way.

So it gets faster, and so now

He provides courses for Maths and Science at Teachoo. So here is that same situation over here, here is that glass piece, He has been teaching from the past 9 years. 1.When the glass slab of thickness t and refractive index μ is placed in the path of a convergent beam as shown in the figure(15.31 a), then the point of convergence is shifted by . Shifted sidewards a little bit glass, it can be any medium as long as its opposite Suppose the ray of light So you see, this is not limited Which means, the two bendings cancel out because they are in So, by using this, we can
Then, the same thing must And the Perpendicular distance between the 2 rays is called Lateral Displacement, The ray of light emerges Right, now you may be wondering, "Well what's the big deal? And if you could draw a normal, we see that the car keeps

Sides which are, again, The thickness of a glass slab is 0.2 m 0.2m 0.
