Question

What are the laws of refraction??????????

Answer 1

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.

Answer 2

Laws of Refraction of Light

Laws of refraction state that:

1. 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.
2. 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.The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.

$\frac{sin \: i}{sin \: r} = constant$
