Fill up the blanks:
The speed of light in glass is `(2xx 10^8 m//sec)`. The speed of light in air is `(Take (mu_g//mu_alpha) = _alphamu^g = 1.5]`

The speed of light through diamond (mu_0 = 2.4) is 1.25 xx 10^8 m//sec . The speed of light in air (mu_n = 1.0) and glass (mu _ v = 1.5) in (m/sec) respectively are.

What is speed of light in glass if its refractive index is 1.5?

Fill in the blank spaces with appropriate answers: The refractive indices of water and glass are (4/3) and (3/2) respectively. If the speed of light in water is 2.25 xx 10^8 m//s) then the speed of light in glass is _______ m/sec.

Fill in the blank spaces with appropriate answers. The speed of yellow light in glass is _______ speed of red light.
