define refraction of light with its laws
Answers
Definition:
Refraction is due to change in the speed of light as it enters from one transparent medium to another
in other words, bending of ray of light as it passes from one medium to another.
the bending of light is called refraction.
Laws of Refraction:
1) The incident ray, refracted ray and normal to the interface of given two transparent media, all lie in same plane.
2) The ratio of sine of angle of incidence and sine of angle of refraction is always constant for the light of given colour and for the pair of given media.
The Second Law of Refraction is also known as Snell’s Law of Refraction.
[EQUATION IS GIVEN ABOVE]
The constant is called refractive index of the second medium in relation to the first medium.
The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different density. The ability of the eye to bend light so that an image is focused on the retina.
