The ratio of the speed of light in air to the speed of light in another medium

The speed of light in air is :

State the speed of light

State the speed of light in glass

A monochromatic beam of light of wavelength lamda passes from air into the glass block , write an expression to show the relation between the speed of light in air and the speed of light in glass .

The critical angle of light from medium A to medium B is theta . The speed of light in medium A is v. the speed of light in medium B is

The speed of light depends

The critical angle for light going from medium X into medium Y is theta . The speed of light in medium X is v. The speed of light in medium Y is

The speed of light is maximum in

Orange light of wavelength 6600 Å travelling in air gets refracted in water. If the speed of light in air is 3xx10^(8)ms^(-1) and refractive index of water is 4/3, find : (i) the frequency of light in air, (ii) the speed of light in water, and (iii) the wavelength of light in water.

The laws of reflection or refraction are the same for sound as for light. The index of refraction of a medium (for sound) is defind as the ratio of the speed of sound in air 343 m//s to the speed of sound in the medium. What is the index of refraction (for sound) of water (v=1498 m//s) ? What is the critical angle theta , for total reflection of sound from water?
