Question

If a converging beam of light is incident on a concave mirror, the reflected light:

• A. may form a real image
• B. must form a real image
• C. may be a parallel beam
• D. may form a virtual image

Answer 1

Answer: (A), (C), (D)

The correct options are
A may form a real image
C may be a parallel beam
D may form a virtual image

$\frac{1}{v}+\frac{1}{u}=\frac{1}{f}$
$\frac{1}{v}=-\frac{1}{u}+\frac{1}{f}$
three possibilities arise here in this situation
case1- if $u=f$ then image is formed at infinity
case2- if $u<f$ then $v<0$ real image is formed
case3- if $u>f$ then $v>0$ virtual image is formed
option $A,C,D$ are correct
