Question

A small air bubble is inside a transparent cube of
side length 24 cm and of refractive index 4 /3. If
the apparent distance air bubble from a face is
9 cm then its apparent distance from opposite face
is
a 6 cm
b) 8 cm
e) 9 cm
d) 12 cm​

Answer 1

Answer:

Answer is 9 cm

Explanation:

We know that (Real depth) / (Apparent depth) =μ

Now, According to question,

9

real depth

​  

=  

3

4

​  

 

⇒ real depth = 12cm.

Which implies that the air bubble is in the middle of the cube. so, from the other side also  the real depth is 12cm. so, the apparent distance from the other end is also 9cm.
