(A)
(B)
(C)
(D)
The correct fixing of the pins P1 and P2, for 'defining the incident ray, and of pins P3 and
P4, for finding the emergent ray' has been done by student: (1)
a. A
lemon kept in water in a bowl is viewed from outside, it appears
the emergent ray, has been done by student: (1)​

Answer 1

Explanation:

OPTION (c)

When light Ray goes from rarer medium to a denser medium it bends towards the normal.

When light goes from a denser medium to a rarer medium, it bends away from the normal.

The principle of reversibility states that light retraces the same path if the direction of travel of light is reversed.

So in this case light Ray goes from rarer medium to a denser medium it bends towards the normal. By observed graphics we can clearly say that option (c) is correct option.
