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

State the relation of velocity of light with refractive index.

Statement I : The velocity of light rays of different colours is the same. But the velocity of the light rays are different for any other medium. If v = velocity of light in the respective medium c = velocity of light in vacuum, mu = refractive index, then v = ( c )/(mu) . Statement II : mu is different for different media.

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

Velocity of light ____cm/sec.

Which colour of light has the maximum refractive index?

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

If water is heated, how refractive index of will change?

Refractive index of glass is 1.5. What is the velocity of light in glass?

If the velocity of light in a medium is 2xx10^9 m//s What will be the refractive index of that medium?
