Question

3. The angle of incidence is
(a) the angle that the incident ray makes with the mirror.
(b) the angle that the incident ray makes with the normal at the point of incidence.
(c) 180° minus the angle that the incident ray makes with the mirror.
(d) the angle that the incident ray makes with the reflected ray.
formed by a nlane mirror is​

Answer 1

Answer:

• The angle of incidence is the angle which the ray makes with the normal at the point of incidence.
• Angle of incidence is equal to the angle of reflection.
• Where deviation is from a single plane mirror it is equal to 180 -2i where i is angle of incidence.

Some more information:

• The angle made by the incident ray with the plane is called glancing angle of incidence.
• The angle made by the reflected ray with the plane is called glancing angle of reflection.
• Glancing angle of incidence is equal to the Glancing angle of reflection.
