Chapter 25.3, Problem 2bTH
Consider the original double−slit pattern from problem 1, shown at right. Suppose that a third slit of the same width were added halfway between the original two slits as shown in the figure below the pattern. (Note that this results in the distance between adjacent slits becoming half of the original value.)
b. Would point Y be a principal maximum, a minimum, or neither? Explain your reasoning.

Assume the figure below was photographed with red light of a single wavelength i. The light passed through a single slit of width
a and traveled distance L to the screen where the photograph was made. Consider the width of the central bright fringe,
measured between the centers of the dark fringes on both sides of it. Rank from largest to smallest the widths of the central
fringe in the following situations and note any cases of equality. (Use only ">" or "=" symbols. Do not include any parentheses
around the letters or symbols.)
(a) The experiment is performed as photographed.
(b) The experiment is performed with light whose frequency is increased by 50%.
(c) The experiment is performed with light whose wavelength is increased by 50%.
(d) The experiment is performed with the original light and with a slit of width 2a.
(e) The experiment is performed with the original light and slit and with distance 2L to the screen.

Mirror M, in the figure below is moved through a displacement AL. During this displacement, 240 fringe reversals (formation of
successive dark or bright bands) are counted. The light being used has a wavelength of 634.8 nm. Calculate the displacement AL.

Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your
calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. µm
