Question

In the figure below, two isotropic point sources S1 and S2 emit light at wavelength A = 400 nm. Source S: is located aty = 750 nm and source S2 is located at y = -7 50 nm. At point P1 (at x = 247 0 nm), the wave from S: arrives ahead of the wave from S1 by a phase difference of 0.500.T rad. What multiple of lamda gives the phase difference between the waves from the two sources as the waves arrive at point P2. which is located at y = 2470 nm. (The figure is not drawn to scale.) x lamda If the waves arrive at P2 with equal amplitudes, is the interference there fully constructive, fully destructive, intermediate but closer to fully constructive, or intermediate but closer to fully destructive? fully constructive intermediate, closer to fully constructive intermediate, closer to fully destructive fully destructive

Explanation / Answer

a)0.25*lembda

2*pie/lembda*delta x=delta phi

delta phi=0.5 pie

so delta x=0.25*lembda

b)fully destructive
