Fig, here shows P and Q as two equally intense coherent sources emitting radiations of wavelength 20m. The separation PQ si 5m, and phase of P is ahead of the phase Q by `90^(@)`. A, B and C are three distant points ofobservation equidistant from the mid - point of PQ. The intensity of radiations of A, B, C will beasr the ratio

Figure here shown P and Q as two equally intense coherent sources emitting radiations of wavelength 20 m. The separation PQ is 5.0 m and phase of Q is ahead of the phase of P by 90^(@) . A,B and C are three distant points of observation equidistant from the mid-point of PQ. The intensity of radiations at A,B and C will bear the ratio

If A=(1,2,3) and B(3,5,7) and P,Q are the points on AB such that AP=PQ=QB , then the mid point of PQ is

If A =(1,2,3) and B=(3,5,7) and P, Q are the points on AB such that AP= PQ =QB,then the mid point of PQ is

S_(1) and S_(2) are two equally intense coherent point second sources vibrating in phase. The resultant intensity at P_(1) is 80 SI units then resultant intensity at P_(2) in SI units will be

Two coherent point sources S_1 and S_2 vibrating in phase emit light of wavelength lamda . The separation between them is 2lamda . The light is collected on a screen placed at a distance Dgt gt lamda from the slit S_1 as shown. The minimum distance, so that intensity at P is equal to the intensity at O
