Question

law of refraction ..............​

Answer 1

Answer:

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.

The exact mathematical relationship is the law of refraction, or “Snell's Law,” which is stated in equation form as n1 sinθ1 = n2 sinθ2. Here n1 and n2 are the indices of refraction for medium 1 and 2, and θ1 and θ2 are the angles between the rays and the perpendicular in medium 1 and 2, as shown in Figure 3.

Answer 2

laws of refraction :-

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 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.

sin i / sin r = n whereby n is the refractive index of the denser medium.
