Write the laws of refraction of light.(b) Define power of a lens) |
|
Answer» The law of refraction, which is generally known as Snell's law governs the behave of light rays as they propagate across a sharp interface between two transparent dielectric media. 1. the incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.2. For the light of a given color and for given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. sin i/ sin r = constant Power of lensis the ability of thelensto converge the rays of light falling on it. It can also bedefinedas P=1/f where f is the focal length. S.I. unit ofpoweris D(Dioptre). It is represented by letter 'P'. |
