Question

sini=n, sinr is called ............ law​

Answer 1

Answer:

Snell

′

s law:− When a ray of light passes from medium-1 to medium-2, then the ratio of sine of angle of incidence(i) to sine of angle of refraction(r) is equal to the refractive index of medium-2 (n

2

) relative to medium-1 (n

1

).

sinr

sini

n

sini=n

2

sinr

This is Snell's Law.

The angle that the incident, reflected, and refracted rays make with the surface normal are called the angles of incidence, qi , reflection, qr, and refraction, qt, respectively. The refractive index of medium 1 is n1 and of medium 2 is n2. Illustration of incident, reflected, and refracted rays.

Explanation:

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
