Question

What is the law of refraction of light ??​

Answer 1

Explanation:

Laws of refraction of light(Snell�s law of refraction) Refraction is due to change in the speed of light as it enters from one transparent medium to another. ... The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane.

Answer 2

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

Law of refraction of light :-

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

• The ratio of the sine of the angle of incidence to the sine of angle of refraction is constant for a given pair of media.

This law is also known as snell's law of refraction.

$\boxed{\sf</strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{ </strong><strong>\frac{sin \: i \: }{sin \: r \: } = c</strong><strong> }}$

The constant value is the refractive index for a given pair of medium .

It is the refractive index of second medium with respect to first medium.
