Answer 2

The primary mirror in a telescope is correct to direct the rays to a particular Focal Point to intensify them.

Option B

Explanation:

• Concave mirror is used as the primary mirror in a telescope.

• The convex mirror  is a  diverging mirror where as a concave mirror is a converging mirror. The converging mirror is used to convert the rays of light which are coming from infinity to a particular focal point.

• As a result of this the intensity of the light is coming from infinity is increased. This increases the visibility of the image. Then a lens is used to view the image with certain magnification.
