A luminous point object is placed at O, ...

A luminous point object is placed at O, whose image is formed at I as shown in Figure. Line AB is optical axis. Which of the following statement is`//`are correct?

A

If a lens is used to obtain the image, then it must be a converging lens and its optical center will be the intersection point of line AB and OI

B

If a lens is used to obtain the image, then it must be a diverging lens and its optical center will be the intersection point of line AB and OI

C

If a mirror is used to obtain the image, then the mirror must be concave and the object and image subtend equal angles at the pole of the mirror.

D

I is a real image

Text Solution

Verified by Experts

The correct Answer is:
a., c., d

Image is inverted, so its should be real.
