Question

Assertion : A virtual image can not be obtained on a screen.
Reason : Two plane mirrors placed parallel to each other, will form infinite virtual images for a real object placed between the mirrors.
Choose the correct option:

• A. Both assertion and reason are true and reason is the correct explanation for assertion.
• B. Both assertion and reason are true but reason is not the correct explanation for assertion.
• C. Assertion is true but reason is false.
• D. Assertion is false but reason is true.

Answer 1

The correct option is B Both assertion and reason are true but reason is not the correct explanation for assertion.

Virtual images can not be obtained on screen because they are not formed by real intersection of light rays. Only real images can be obtained on a screen.

A plane mirror always forms a virtual images of an object. When two plane mirrors are placed parallel, then $\infty$ number of images are formed.
$\therefore$ Assertion and reason are correct but reason is not an explanation of assertion.
