Question

1. 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. e 180° minus the angle that the incident ray makes with the mirror d. the angle that the incident ray makes with the reflected ray.​

Answer 1

Answer:

THE PROCESS BY WHICH GREEN PLANTS PREPARE THEIR OWN FOOD IS CALLED PHOTOSYNTHESIS

Answer 2

The correct option to the above question is (b).

• The angle of incidence is the angle that the incident ray makes with the normal at the point of incidence.
• In optics, when if a ray of light gets incident on the surface, then the angle which ray of light makes with the surface and the line perpendicular to the surface at the point of incidence is called the angle of incidence.
• The Law of reflection states that when the light gets incident on the surface, it makes two angles, one is the angle of incidence, and the other angle of reflection and the angle of reflection is always equal to the angle of reflection.
