Question

State :-
a) The laws of Reflection .
b) The laws of Refraction .​

Answer 1

Answer:

1. The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
2. 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. This is also known as Snell's law of refraction.

$\tt \underline \red { 1. law \: of \: reflection}$

The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.

$\tt \underline \red{2. law \: of \: refraction}$

The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. This is also known as Snell's law of refraction.
