Four identical monochromatic sources A,B...

Four identical monochromatic sources A,B,C,D as shown in the (figure) produce waves of the same wavelength `lambda` and are coherent. Two receiver `R_(1)` and `R_(2)` are at great but equal distances from B.
(i) Which of the two receivers picks up the larger signal when B is turned off?
(iii) Which of the two receivers picks up the larger singnal when D is turned off ?
(iv) Which of the two receivers can distinguish which of the sources B or D has been turned off ?

Four identical coherent sourc e emiting monochromatic light if same wavelength lambda are placed at A,B,C and D as shown. Two receivers R_(1) and R_(2) are at but equal distance from B. The path difference between signals reaching from A&D at R_(1) is (lambda)/(2) and between signals reaching from A & B at R_(2) is ~= 0 . Also assume that intensities of waves emitted by A,B,C &D reaching at R_(1) and R_(2) is same.
