Question

When a number of rays coming parallel to each other strikes a concave mirror then they neet at focus or focal plane?

Answer 1

Answer:

they meet at focus is the correct answer

Answer 2

Answer:

When a number of rays coming parallel to each other strike a concave mirror then they meet at focus.

Explanation:

• Curved surfaces with painted edges can be found on each side of spherical mirrors.
• A spherical mirror is referred to as a convex mirror if the interior surface has been painted.
• The reflective surface of a concave mirror is curved inward and away from the light source.
• The focus is the location where two things converge or diverge.
• A concave mirror's principal focus is a location on its principal axis where all parallel light rays will converge after reflecting off of the concave mirror.
• A concave mirror's focal plane is a plane that runs across its focus and is perpendicular to the concave mirror's main axis. The picture at the focal plane is created by parallel incident rays that are reflected at the concave mirror's surface.

Thus, when a number of rays coming parallel to each other strike a concave mirror then they meet at focus.
