Question

explain the laws of refraction ??​

Answer 1

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

$:\implies$ The angle of incidence is the angle between the incident ray and the normal; denoted as ‘i’.

$:\implies$ The angle of refraction is the angle between the refracted ray and the normal; denoted as ‘r’. Laws of refraction state that:

$:\implies$ The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane.

$:\implies$ The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.

Answer 2

Laws of refraction state that:
1)The incident ray, reflected ray and the normal, to the interface of any two given mediums, all lie in the same plane.

2)The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant. This is also known as Snell's law of refraction.
