The refractive index of a medium tells you how much the speed of light has reduced.

Define refractive index of a medium.

Refractive index of a medium depends on

How is the refractive index of a medium related to the speed of light ? Obtain an expression for refractive index of a medium with respect to another in terms of speed of light in these two media ?

(a) Compare the speed of light of wavelength 4000 Å (i.e., violet light) and 8000 Å (i.e. red light) in vacuum. (b) How is the refractive index of a medium related to the speed of light in it and in vacuum or air ?

The refractive index of water is 1.33. What will be the speed of light in water

The refractive index of glass is 1.5. Find the speed of light in glass.

(I) How does the refractive index of a medium depends on the wavelength of light used? (II)Which is greater, angle of incidence or angle of refraction, when light travels from denser medium to rarer medium.

How does the refractive index of a medium depend on the wavelength of light used ?

Define the term refractive index of a medium in terms of velocity of light.

If the refractive index of ice is 1.31, what will be the speed of light in it?
