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:
Answer & explanation
Correct answer: option 2
Distance of the object (star) is infinitely large. Hence the light coming from star will converge at its focal point.
Hence distance of image is $ v = f = \frac{R}{2} = 1m$
