Light enters from air to diamond which has refractive index of 2.42. Calculate the speed of light in diamond . The speed of light in air is 3.0 xx 10^8 m s^-1

What is the Brewster angle for air to glass transition? (Refractive index of glass is 1.5)

When white light travels through glass the refractive index mu=(velocity of light in air/velocity of light in glass) is found to very with waveless as mu=A+B/lambda^2 where A and B are constants. Using the principle of homogeneity of dimensions, determine the SI unit in which A and B must be expressed.
