The apparent depth of an object at the bottom of a tank filled with a liquid of refractive index 1.3 is 7.7 cm. What is the actual depth of the liquid in the tank?​

The apparent depth of an object at the bottom of a tank filled with a liquid of refractive index 1.3 is 7.7 cm. What is the actual depth of the liquid in the tank?

REFRACTIVE INDEX = 1.3

APPARENT DEPTH = 7.7 cm

REAL DEPTH OF THE OBJECT.

Refractive Index = 1.3

Apparent Depth = 7.7 cm

Putting the values in the formula:-

continuous conducting path for current, power supply
