reflection of light is a process of
Which is best reflector of light?
angle of reflection=
angle of reflection=angle of incidence
An incident ray makes an angle of 35 degree with the surface of a plane mirror .What is the angle of reflection?
Here, the angle is given with the surface of mirror not the normal. So the angle of incident ray with the normal
= 90-35 = 55°
Now, we can say
Angle of incidence =angle of reflection= 55 degree
David is observing his image in a plane mirror. The distance between the mirror and imag is 4 m. If he moves 1 m towards the mirror then the distance between david and his image will be
distance of david from mirror = 4m - 1m = 3m
distance of image from mirror = 3m
total distance 3m + 3m = 6m
