Answer 1

Answer:

State the two laws of reflection.

State the two laws of reflection.Ans. The laws of reflection are as follows: The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.

Give one use of a convex mirror and a concave mirror along with the reason

Ans. A large Concave Mirrors are used in the field of solar energy to focus sun rays for heating solar furnaces. A Convex Mirror is that is spherical mirror in which the reflection of light takes place at the convex surface. Convex Mirror are used as rear view mirror in vehicles to see the traffic at the rear side.
