As shown in the figure, a plane mirror is fixed at a height of50 cmfrom the bottom of tank containing waterμ=43. The height of water in the tank is8 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.

Question diagram: As shown in the figure, a plane mirror is fixed at a height
Answer:
98.00
Solution:

The data given is 

d=8 cmμ=43

Apparent depth is

 h'=dμ=843=6 cm
Distance of object from mirror =42+6=48 m
Distance of image from bottom of tank =48+50=98 m
