Answer 1

Answer:

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.

Explanation:

(1) The ratio of sine of angle of incidence to the sine of angle of refraction for a particular pair of media is constant. Therefore, if

angle of incidence = i

angle of refraction = r

sinr/

sini =constant

The value of this constant depends upon temperature and wavelength of light. This is also known as Snell's law.

(2) The incident ray, the refracted ray and the normal at the point of incidence, all the lie in the same plane.

Refractive index (of a medium) = speed of light in air (or vaccum) / speed of light in medium
