Among the two interfering monochromatic sources

A\;and\;B

;

A

is ahead of

B

in phase by

66^\circ

. If the observation be taken from point

P

, such that

PB - PA = \lambda /4

. Then the phase difference between the waves from

A\;and\;B

reaching

P

is

View answer and explanation

Correct option: A

156^\circ

Option A (

156^\circ

) is correct because the total phase difference is the sum of the initial phase difference and the phase difference due to the path difference.
