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.

Answer 2

Whensoever a light ray emerging from a source strikes a polished reflecting surface at certain angle of incidence (i) , it reflects at an angle of reflection (r) equal the incident angle . This phenomenon is called Reflection of Light.

A reflecting light follows two governing laws. They are:

• Incidence angle is always equal to reflecting angle for a light ray.
• The Normal , the incident point and the reflecting point all lie on a single point located on the same plane.
