Question

State the laws of refraction. why do different media have different refractive index?
Diamond Refraction Index is 2.42 what it means.
(please write in Book and send pic kind request)​

Answer 1

Laws of refraction state that: ... The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.

Answer 2

Answer:

Laws of refraction :--

The incident ray, the reflected ray and the normal , to the interface of any two given mediums and all lie on the same plane.

The refractive index varies with wavelength linearly because different wavelength interfere to different extents with atoms of the medium .
