Chapter 34, Problem 62GP
Two identical sources S1 and S2, separated by distance d, coherently emit light of wavelength λ uniformly in all directions. Defining the x axis with its origin at S1 as shown in Fig. 34-32, find the locations (expressed as multiples of λ) where the signals from the two sources are out of phase along this axis for x > 0, if d = 3λ.

drawn to scale, the ray is incident at the critical angle on the inter-

Also, let the center disk be rotated on the common axis with an angular speed . Show that if unpolarized light is incident on the left disk with an intensity Imax, the intensity of the beam emerging from the right disk is I=116Imax(1cos4t) This result means that the intensity of the emerging beam is modulated at a rate four times the rate of rotation of the center disk.
