Q. If white light is used in the Newton’s rings experiment, the colour observed in the reflected light is complementary to that observed in the transmitted light through the same point. This is due to
A) $90{^\circ}$ change of phase in one of the reflected waves
B) $180{^\circ}$ change of phase in one of the reflected waves
C) $145{^\circ}$ change of phase in one of the reflected waves
D) $45{^\circ}$ change of phase in one of the reflected waves
Explanation
The correct answer is Option A: $90{^\circ}$ change of phase in one of the reflected waves.
