Answer:
The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface. ... Light is diffused when it reflects from a rough surface.

Answer:
1-The bouncing back of ray if light after striking any reflecting surface is known as reflection of light.
2-All incident,normal and reflected rays lies on same plane.
Angle of incidence is equal to angle of reflection.
3- 90 degree
5-image is virtual,erect,same size of objects, laterally inverted.
Explanation:
6-plane mirror used as face mirror
it also used in shops for protecting from robbery.
7-The phenomenon in which right side part seen in left and left side part seen in right in , This phenomenon is known as lateral inverted.
