In the figure shown S and S are two coherent sources emitting light of wavelength A and having zero initial phase difference S and S oscillate simple harmonically with amplitude a each and angular frequency w each on line PQ which is perpendicular to x axis The initial position and initial direction of motion of S and S are shown S and S are at their mean position at t 0 Then rate of change of fringe width at time t is XDw T 3w a x then x 2y equals Assume that a and a D and x y are integers B c urfuch cellar m 3 fa XDw 2 a x y 2a 2a z 3ad su atma ge urfag Kufa au uefug fe teft 1 x y quic1 P S u 2 aface Gaung Haar Gad T 3w S J t 0 g f 43 uz 31 2 uRada 6z ar Hai fch a D Correct Answer 10
