Question
Problem 5: A diffaction grating is illuminated with coherent (laser) light with wavelength d<d and oscillation period7 = X/c where d is the spacing between adjacent slits in the grating. The 4h order intensity maximum, to the left of the central intensity maximum M, is located at point P, as shown in figure below. A wave crest A from slit R and a wave crest B from the neighboring slit S, to the right of R. have both departed at the same time from their respective slits of origin. Therefore, at P. Fig. 2.40 R S Diffr. Grating 11 Laser Beam (A) A will arrive 3 periods before B. (B) A will arrive 4 periods before B. (C) A andB will arrive at the same time. (D) B will arrive 3 periods before A. (E) B will arrive 4 periods before A. P.
