2.concave mirror

Explanation:

Answer 2

1. b) Spherical mirrors have curved reflecting surface.
2. b) Concave mirror has reflecting surface curved inward.

Explanation:

• Spherical mirror is a mirror with a surface that is either concave or convex and forms a portion of a true sphere.

• One side of such mirrors is well polished and reflecting and the other side is opaque.

• It has a shape of a piece cut out of a spherical surface.

• There are two types of mirrors: convex and concave.

• Reflective surface of a concave mirror is on the side curved inwards. They are generally used as shaving mirrors or by dentists and even in telescopes.

• Concave mirrors are also called converging mirrors.
