For which medium is. refractive index `(mu)` is
maximum?

For which medium is. refractive index (mu) is minimum?

What is the refractive index of a medium?

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

A ray of light passing through the medium of refractive index mu_(1) is incident on the surface of separation of another medium of refractive index mu_(2) . A part of the ray is reflected and another part is refracted. What should be the angle of incident so that reflected ray and the refracted ray are at right angles to each other?

Define absolute refractive index.

What is the unit of refractive index ?

A monochromatic ray of light is refracted from vacuum to a medium of refractive index mu . Determine the relation of the wavelengths of light in vacuum and in medium.

A light ray travels from vacuum into a medium of refractive index mu . If angle of incidence is twice the angle of refraction then calculate the angle of incidence.

What will be the velocity and wavelength of a light in a medium, of refractive index 1.5 if the wavelength of that is 6000 overset(0)A in air medium?
