n = [(R/2)2 + t2]1/2/R/2
t is the thickness of the glass plate, R is the inner radius of the outer bright ring you see

How to derive lateral shifting formula?
When a ray of light from a medium is incident on another medium with different optical density, the ray bends due to refraction. The perpendicular distance between the emergent ray and the incident ray is called the lateral shift. The angle which the incident ray makes with the normal is called angle of incidence denoted by 'i' and the angle made by the refracted ray with the normal is called the angle of refraction denoted by 'r'. Lateral shift is given by the formula:- Where t is the thickness of the glass slab, i is the angle of incidence and r is the angle of refraction
What is it called when glass bends light?
REFRACTION
What happens to some of the light before entering a glass block?
When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.
To make the smaller glass disappear that is make it appear to be invisible How would the index of refraction of the liquid inside have to compare to the index of refraction of the glass?
You want the ior of the glass to be identical to the liquied.
What has the highest index of refraction a vacuum a diamond air or crown glass?
A diamond has the highest index of refraction, about 2.4 Crown glass is about 1.5 and a vacuum is 1
Why should the ray emerging from the glass block come out parallel to the incident ray?
The ray comes out parallel to the incident ray because the ray has the opposite refraction as when it entered the block.
Why emergent parallel incident ray in a glass slab?
This is because the amount of refraction taking place at the parallel faces of a glass slab is equal but opposite and since the faces are parallel the emergent ray emerges parallel to the incident ray with lateral displacement.
What do you have to do for Refraction through a rectangular glass block?
when a parallel beam hit the rectangular glass it will gave a refraction.
What does glass produce?
glass can produce a refraction (bending) of light
What produces glass?
glass can produce a refraction (bending) of light
