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 the reflected Waves
Correct Answer: B
Solution :
The rings observed in reflected light are exactly complementary to those seen in transmitted light. Corresponding to every dark ring in reflected light there is a bright ring in transmitted light. The ray reflected at the upper surface of the air-film suffers no phase change while the ray reflected internally at the lower surface suffers a phase change of\[\pi \].You need to login to perform this action.
