Answer» 1.Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The laws of reflection are as follows:i).The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.ii).The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.iii).The reflected ray and the incident ray are on the opposite sides of the normal.2. |
