 The figure shows two spherical mirrors. The mirror whose reflecting surface curves **inward** (toward the object being reflected) is called:
APlane mirror
BConcave mirror
CConvex mirror
DCylindrical mirror
Answer & Solution
Correct answer: B. Concave mirror
A spherical mirror whose reflecting surface curves inward (toward the object) is a **concave** mirror; one whose reflecting surface curves outward is a **convex** mirror. The terminology mirrors the lens convention (con-cave = cave-shaped, hollow).
