Solution

The correct option is B
Below 'O'

To find the position of image I, we will draw a ray diagram.

An image is formed where two reflected or refracted rays meet or appear to meet.

Clearly, when we see 'O' from RS, the two refracted rays appear to meet at 'I" below 'O'.

Q. In the diagram shown below, a point source O is placed vertically below the center of a circular plane mirror. The light rays starting from the source are reflected from the mirror such that a circular area A on the ground receives light. Now, a glass slab is placed between the mirror and the source O. What will the magnitude of the new area on the ground receiving light? Assume the width of the slab to be very large.
