Question

what is refraction in physics explain​

Answer 1

When light travels from one transparent medium to another transparent medium, it bends from its original path. This phenomenon of bending of light is called refraction. Refraction takes place at the boundary of separation of the two media.

Answer 2

$\large{\pmb{\underline{\underline{\sf{Refraction:-}}}}}$

Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina.

$\large{\pmb{\underline{\underline{\sf{Examples~ Of~ Refraction:-}}}}}$

Bending of the sun's rays as they enter raindrops, forming a rainbow.

$\large{\pmb{\underline{\underline{\sf{Laws~ of~ Refraction:-}}}}}$

The angle of incidence is the angle between the incident ray and the normal; denoted as ‘i’. The angle of refraction is the angle between the refracted ray and the normal; denoted as ‘r’.

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.
