Question

Calculate real and depth if refractive index of glass is 1.5 and object below it appear at 9 cm​

Answer 1

Explanation:

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 = 1.5 9

+

1.3

6

=6+4.6

=10.6 cm

Apparent depth of newspaper is 10.6 cm.
