A concave mirror has radius of curvature 2 m. Light from a distance star is incident on the mirror. The distance of the image of the star from the mirror is :
- A Infinite
- B 1 m
- C 2 m
- D 0.5 m
Answer & Solution
Correct Answer
(B) 1 m
Step-by-step Solution
Detailed explanation
Radius of curvature \( R = 2 \text{ m} \) Focal length \( f = R/2 \) \( f = 2 \text{ m} / 2 = 1 \text{ m} \) For a distant object (star), the image forms at the focal point. Image distance \( = 1 \text{ m} \)
