1.A circular diffraction pattern is formed on a faraway screen.
(a) By what factor will the width of the central maximum change if the wavelength is doubled?
(a) 4
(b) 2
(c) 1 (no change)
(d) 1/2
(e) 1/4
(b) By what factor will the area of the central maximum change if the slit width is doubled?
(a) 4
(b) 2
(c) 1 (no change)
(d) 1/2
(e) 1/4

2. Consider a Young's two-slit experiment in which the wavelength of light is 38% smaller than the distance between
the slits.
(a) How many complete dark fringes would be seen on a distant screen? (Assume for all these questions that
the screen is as large as it needs to be.)
(a) 0
(b) 1
(c) 2
(d) 3
(e) 4
(f) 5
(b) How many total interference maxima would be seen on a distant screen?
(a) 0
(b) 1
(c) 2
(d) 3
(e) 4
(f) 5
(c) Now suppose that the wavelength of light is 134% larger than the slit separation. How many complete dark
fringes would be seen on a distant screen?
(a) 0
