Question

the refractive index of glass is 3/2. the apparent depth is _ of the real depth​

Answer 1

Answer:

We use

μ=

Apparent depth

Real depth/thickness of theobject

Due to refraction at two boundaries, the apparent depth of the newspaper will be

Apparent depth=

μ

glass

Thickness of the glass

+

μ

water

Thickness of the water

=
