law of refraction of light and also express it mathematically.
Answers
Answer:State Snell's law for refraction of light and also express it mathematically. The refractive index of air with respect to glass is 2/3 and the refractive index of water with respect to air is 4/3. ... When a ray of light travels from one transparent medium to another, it bends at the surface.
Explanation:
Answer:
following are the laws of reflection of light.
(i) The incident ray, the refracted ray and normal to the interface of two transparent media at the point of incidence, all lie in the same plane.
(ii) The ratio of sine of incidence to the sine of angle of refraction is a constant, for the light of a given colour and for the given pair of media. This law is also known as Snell's law of reflection. (This is true for angle 0 < i < 90°) If i is the angle of incidence and r is the angle of refraction, then,
sin I/ sin r = constant.
Reflection of light means bending of light in different media.
