Question

explain refraction of light.​

Answer 1

Answer:

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction

Answer 2

Step-by-step explanation:

Refraction:-

Refraction is the bending of a wave when it enters a medium where its speed is different. We can define it as the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

Laws of refraction state that:

• 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.

sin i/sin r = constant

μ1 sin i = μ2 sin r
