Question

A man of height $H$ is standing in front 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 seperation between eyes and head of men)

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

Answer 1

Answer: (C)

$zero$

• Zero light would be seen as light after reflection would never reach the person's eyes.
  
• His face's light after refelection would go downward not to his eyes and the extreme light i.e, of his foot after reflection would just pass over his head.
