2 sources S1 and S2 eitting light of wavelength 600nm are placed a distance 1.0 X 10^(-2)cm apart. A detector can be moved on the line S1P which is perpendicular to S1S2. Locate the position of the farthest minimum detected.the answer given as solutionstarts as :"The farthest minimum occurs at a point P where the path difference is lambda/2"Explain this sentence as why it is so.and solve the question.
