Position of a Single Photon at a Screen. Consider monochromatic light of wavelength X. incident on an infinite screen in the plane z = 0, with an intensity I(p) = Io exp(-p/po), where p = Vx2 + y². Assume that the intensity of the source is reduced to a level at which only a single photon strikes the screen. (a) Find the probability that the photon strikes the screen within a radius po of the origin. (b) If the incident light contains exactly 106 photons, how many photons strike within a circle of radius po on average? %3D
