The depth of a bucket filled with water seems to be lecet
actual depth. Name the phenomenon responsible for this?
2 Alight ray is incident on a rectangular glass slab at an angle of
60°. What is the angle between the ray coming out of the slab
and the normal to the face of rectangular slab from which i
comes out?
3) How is the refractive index of a medium related to the speed of
light? Give an expression for refractive index of a medium with
respect to another in terms of speed of light in these two
media?
4 For the same angle of incidence, the angle of refraction in
three different media A, B and C are 10°, 25° and 40°
respectively. In which medium the velocity of light will be
maximum?
5 Calculate the angle of incidence of light ray incident on surface
of a plastic slab of refractive index 3, if the angle of refraction
is 30°
[Ans. 60°)
6 If a ray of light enters from alcohol to air. The refractive index of
alcohol is 1.36. Calculate the speed of light in alcohol with
respect to air.
[Ans. 2.21% 10% ms']
