Question

A transparent cube of 0.21 m edge contains a small air bubble. Its apparent distance when viewed through one face of cube is 0.1 m and viewed from opposite face is .04 m. The actual distance of the bubble from the second face of the cube ?​

Answer 1

Answer:

0.06m

Explanation:

refractive  index =real deepth÷apparent depth      

x/0.04=0.21-x/0.10

⇒0.21×0.04-x× 0.04=0.10x

⇒x=0.21×0.04/0.14

⇒     0.06m
