Answer 1

Answer:

1. Concave mirror

2. Pole of the mirror

3. r=2f

Answer 2

QUESTIONS...

1. A MIRROR IN WHICH THE INNER HOLLOW SURFACE IS THE REFLECTING SURFACE IS CALLED AS..

ANSWER - CONCAVE MIRROR

REASON - concave mirror is a part of spherical mirror .

2.THE GEOMETRICAL CENTER OF A SPHERICAL MIRROR IS CALLED AS. ..

Answer - focal length.

reason - distance from the mirror to the focal point is known as the focal length.

3. WHICH OF THE FOLLOWING RELATIONS IS TRUE FOR SPHERICAL MIRROR?....

ANSWER - r = 2f

reason - the radius of curvature is two times of focal. length.
