Answer» Refractionof Light. Light does not travel in the same direction in all media. It appears that when travelling obliquely from one medium to another, the direction of propagation of light in the second medium changes. Reflection of lightis the phenomenon of bouncing back oflightin the same medium on striking the surface of any object. • The two laws ofreflectionare: (i) the incident ray, thereflectedray and the normal (at the point of incidence), all lie in the same plane. |
