5. When a ray of
light passes
obliquely from
one medium to
another, it
undergoes a
deviation at the
surface of
separation of the
two media
6. The velocity of light
will be higher in a
medium of low optical
density and vice versa
Ascending order of
optical density
air < water < glass <
diamond
7. No deviation takes place when the
ray of light passes normally from
one medium to another

10. The spoon seems to be bent
due to refraction
It is due to refraction we
see the fish just above the
real position
11. Do you think
that you are
seeing the sun
rise and sun
set at the
correct time
when sun
rises and sets?
12. The mirache we see on
road in sunny days is
caused by refraction!
