Question

1. which type of curved mirror uses its inside as the reflecting surface? (1 point)

a convex mirror
a concave mirror
a virtual mirror
a plane mirror

Explanation:

A concave mirror is a curved mirror where the reflecting surface is on the inside (the concave side). A convex mirror has the reflecting surface on the outside. A virtual mirror is not a standard type of curved mirror classification in basic optics (it refers to the nature of the image in some cases, not the mirror type). A plane mirror is flat, not curved.

Answer:

a concave mirror
