At night many people see rings (called entoptic halos) surrounding bright outdoor lamps in otherwise dark surroundings. The rings are the first of the side maxima in diffraction patterns produced by structures that are thought to be within the cornea (or possible the lens) of the observer’s eye. (The central maxima of such patterns overlap the lamp.) (a) Would a particular ring become smaller or larger if the lamp were switched from blue to red light? (b) If a lamp emits white light, is blue or red on the outside edge of the ring?

The full width at half-maximum (FWHM) of a central diffraction maximum is defined as the angle between the two points in the pattern where the intensity is one-half that at the center of the pattern. (See Fig.36-8b.) (a) Show that the intensity drops to one-half the maximum value when sin2α=α22. (b) Verify that α=1.39rad. (about 80°) is a solution to the transcendental equation of (a). (c) Show that the FWHM is Δθ=2sin-10.443λ/awhere a is the slit width. Calculate the FWHM of the central maximum for slit width (d) 1.00λ ,(e) 5.00λ,and (f) 10.00λ.

For the situation in Questions 9 and Fig. 1, if instead we increased the grating spacing, would (a) the half-widths of the lines and (b) the separation of the lines increase, decrease, or remain the same? (c) Would the lines shift to the right, shift to the left, or remain in place?
