An angle between the incident ray and a plane mirror is….
90 degrees ( EX: angle between the incident ray and a plane mirror is 14 so 90-14 = 76
The law of reflection :
Angle of incident = angle of reflection
Normal
Perpendicular line to a mirror surface
Plane mirror
Flat surface
Plane mirror will have the same SALT characteristics
S= same size, A= upright but laterally inverted, L= same distance behind the mirror, T= Virtual Image
