Question

if a parallel beam of light falls on a mirror in which path light go​

Answer 1

Answer:

It dpends upon the type of mirror used. There can be 3 cases formed:

1) Convex mirror= Here the parallel rays of light will diverge or spread out in all directions.

2) Concave mirror= In this case the rays of light will converge or we can say meet at a point.

3) Plane mirror= In this the light will reflect from an angle by which it hit the plane mirror. Say if a ray light comes from an angle of 30 degree than it will reflect back with the same angle i.e 30 deg.
