Options
- AThe image formed by a concave mirror for an object lying at infinity is at the principal focus, highly diminis
- BA ray of light parallel to the principal axis after reflection from a concave mirror appears to diverge from t
- CThe focal length of a spherical mirror is double of its radius of curvature
- DA ray of light travelling from a rarer medium to a denser medium bends away from the normal
Correct answer
A. The image formed by a concave mirror for an object lying at infinity is at the principal focus, highly diminis
Step-by-step solution
