define refraction
state the law of refraction
Answers
Answer:
the principle that for a ray, radar pulse, or the like, that is incident on the interface of two media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocity of the ray in the first medium to the velocity in the second medium and the incident ray
Answer:
Refraction of Light is a phenomenon wherein light bends and travels from one transparent substance to another.
Laws of Refraction
The laws of refraction govern the behaviour of light as they pass through the interface between two media. It is generally known as Snell’s Law. From the above-depicted activity, we can say that refraction of light follows two laws:
The refracted ray, incident ray and the normal at the interface of two transparent media at the point of incidence, all lie in the same plane.
For the given pair of media, the ratio of the sine of the angle of incidence to the sine of angle refraction is always constant.
sin i/sin r= constant
