Question

A man of height $H$ is standing in font of a mirror, which has been fixed on the ground. What length of his body can the man see in the mirror? The length of the mirror is $\frac{H}{2}$. (Neglect separation between eyes and head of men)

• A. $H$
• B. $\frac{H^2}{{(H^2+L^2)}^{\frac{1}{2}}}$
• C. Zero
• D. $\frac{Z{H}^2}{L}$

Answer 1

The correct option is A $H$

It is clear from the diagram that light ray coming from the eye of the man after reflection on the mirror comes to the lowest point of the man. hence man can see his whole body of length $H$ in the mirror.
