The refractive index of diamond is `2.47` and that of glass is `1.51`. How much faster does light travel in glass than in diamond ?

The refractive index of diamond is 2.47 and that of window glass is 1.51 . Find the ratio of speed of light in glass and diamond.

The refractive index of a transparent material is 1.84 and that of glass is 1.52. By how much amount the light travels faster in a window glass than in the material ?

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

The refractive index of water is 4/3 and that of glass 3/2. A beam of light travelling in wter enters glass. For what angle of incidence the refected light will be completely plane-polarised? (than 48^(@)22 = 1.125)

Assertion : The refractive index of diamond is sqrt(6) and that of liquid is sqrt(3) . If the light travels from diamond to the liquid, it will totally reflected when the angle of incidence is 30^(@) . Reason : mu=1/(sin C) , where mu is the refractive index of diamond with respect to liquid.

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

The refractive index of air with respect to glass is 2//3 . The refractive index of diamond with respect to air is 12//5 . Then the refractive index of glass with respect to diamond will be

The refactive index of diamond and a glass slab is 2.47 and 1.68, respectively. Determine the ratio of speed of light in diamond and glass slab.

The refractive index of glass for light going from air to glass is 3/2 . The refractive index for light going from glass to air will be:
