what is reflection of light . give the law of reflection with a labelled diagram
Answers
Laws of reflection of light:
First law of reflection: According to the first law of reflection, the incidence ray, the reflected ray and normal (at the point of incidence), all lie in the same place. For e.g., in the figure, the incidence ray AO, the reflected ray OP and the normal ON, all lie in the same plane, the plane of paper.
Second law of reflection: According to the second law of reflection, the angle of reflection is always equal to the angle of incidence. For e.g., if we measure the angle of reflection NOB in the figure, we will find that it is exactly equal to the angle of incidence AON.
If the angle of reflection is 45.5
∘
, the angle of incidence will also be 45.5
∘
in accordance with the second law of reflection.
