Question

we get a virtual image in a concave mirror when the object is placed________
A)at f(focus)
B)between the pole and F
C)at c (centre of curvature)
D) beyond c​

Answer 1

between pole and focus

Answer 2

(B) between pole and the focus

Explanation:

the first rule is the parallel light ray should pass through focus ( f ). we know that normal line must go through centre of curvature ( c ) ,both the light Ray's are looking like diverging Ray's they don't meet at at front of prolonged it means they meet at back produce the Ray's infinitely the place the light Ray's are joined there forms the virtual,erected and enlarged formed inside the mirror.
