उत्तर
Apparent depth = 2.7 m
`µw=4/3`
Real depth = apparent depth × 𝛍w
`=2.7xx4/3=3.6 m`

What is the refractive index of water
A ray of light strikes the surface of a rectangular glass slab such that the angle of incidence in air is
- 0°,
- 45°.
In each case, draw a diagram to show the path taken by the ray as it passes through the glass slab and emerges from it.
