Reflection, , Refraction, , , , , , > The process of sending back, the light rays which fall on the, surface of an object, is called, reflection of light., , In reflection of ight, rays are, deflected from the surface of, the medium back same, medium., , Accordingto first law of, reflection of ight, the incidence, ray, the reflected ray, and the, normalaillie in the same, plane., , Accordingto second law of, reflection of ight, the angle of, reflections always equal to, the angle of incidence, , , , Bending of ightwhenit goes, from one medium to another, obliquely is called refraction of, light., , . The refraction of light takes, , place at the boundary between, the two media., , Accordingto the first law of, refraction of light, the incident, ray, the refracted ray and, normalat the point of, incidencealllie in the same, plane., , . According to second law of, , refraction of light, the ratio of, sine of angle of incidence to., the sine of angle of refraction, is constantfora given pair of, media
