Calculate the velocity of light in glass refractive index if glass is 1.5.

The critical angle of glass relative to a liquid is 57^(@)20' . Calculate the velocity of light in the liquid. Given mu of glass = 1.58, Velocity of light in vacuum 3 ×10^(8) m * s^(-1) and sin 57^(@)20' = 0.8418 .

State the relation of velocity of light with refractive index.

Velocity of light in water is 3/4 times the velocity of light in vacuum. Find the refractive, index of water.

For which colour of light is the refractive index of glass a maximum?

If c and c_(1) are the velocities of light in vacuum and in a medium respectively, then the relation of velocity of light with the refractive index of the medium will be

A ray of light enters a rectangular glass block and is incident on the lower face of the block. Angle of incidence is 30^(@) . Part of the ray is reflected inside it and the rest emerges out of the block. Refractive index of glass is 1.5. What is the angle between the emergent ray and the reflected ray? [sin 48^(@) = 0.75]

Statement I : Greater is the refractive index of a medium or denser the medium, lesser is the velocity of light in that Statement II : Refractive index is inversely proportional to velocity.

There is a small pin on a table. The pin is viewed from 50 cm above it. Now without disturbing the pin, a glass slab of 15 cm thickness is held above the pin, parallel to the table top. If the refractive index of glass is 1.5 , calculate the height (in cm) at which (from the pin) the image of the pin is formed.

What do you mean by the statement that refractive index of glass is 1.5?
