Spherical Mirrors (Concave and Convex)Quiz - Solve & Score
Q1. Which mirror gives a wider field of view (NCERT)?
- A.concave mirror
- B.plane mirror only
- C.a concave mirror at the focus
- D.convex mirror
Answer: D. convex mirror
Q2. A concave mirror polished by a planetarium guide at a roadside tea stall has its centre of curvature 16 cm from the pole; how far from the pole is the focus?
- A.4 cm
- B.8 cm
- C.32 cm
- D.16 cm
Answer: B. 8 cm
The focal length of a spherical mirror is half its radius of curvature: f = R/2. Here R = 16 cm, so f = 16/2 = 8 cm.
Q3. If a convex blind-turn mirror surveyed by a jeweller in a curved-mirror gallery curves with radius 16 cm, what focal length does it carry?
- A.8 cm
- B.16 cm
- C.32 cm
- D.4 cm
Answer: A. 8 cm
The focal length of a spherical mirror is half its radius of curvature: f = R/2. Here R = 16 cm, so f = 16/2 = 8 cm.
