→A person lives in a high-rise building on the bank of a river $50\, m$ wide. Across the river is a well lit tower of height $40\, m$. When the person, who is at a height of $10\, m$, looks through a polarizer at an appropriate angle at light of the tower reflecting from the river surface, he notes that intensity of light coming from distance $X$ from his building is the least and this corresponds to the light coming from light bulbs at height $'Y'$ on the tower. The values of $X$ and $Y$ are respectively close to (refractive index of water $ \simeq \frac{4}{3})$
