As shown in the figure, a plane mirror is fixed at a height of 50 cm from the bottom of tank containing water μ = 4 3 . The height of water in the tank is 8 cm . A small bulb is placed at the bottom of the water tank. The distance of image of the bulb formed by mirror from the bottom of the tank is ______ cm .

Correct answer

0

Step-by-step solution

The data given is d = 8   cm μ = 4 3 Apparent depth is h ' = d μ = 8 4 3 = 6   cm Distance of object from mirror = 42 + 6 = 48   m Distance of image from bottom of tank = 48 + 50 = 98   m
