PhysicsInteger+4 / -1Question 22 of 90

A ring is placed at the bottom of a trough containing four immiscible liquids of refractive indices 1.0, 2.0, 3.0 and 4.0 poured one above the other of heights 10 cm, 20 cm, 30 cm, and 40 cm respectively. The apparent depth at which the ring appears, when seen from outside is _______ cm.

Your answer

Answer and worked solution

Official answer: 40

Apparent depth $\sum\frac{h_i}{\mu_i}=\frac{10}1+\frac{20}2+\frac{30}3+\frac{40}4=40$ cm.

Answer: 40
