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.

- The experiment described in question 2 above is performed, but this time, a strip of transparent plastic is placed over the left slit. Its presence changes the interference between light waves from the two slits, causing the interference pattern to be shifted across the screen from the original pattern. Explain, clearly but briefly, which way (right or left) the original pattern shifts and why this shift occurs.arrow_forwardIn a Young's double-slit experiment, blue light (?λ = 440 m) gives a second-order bright fringe at a certain location on a flat screen. What wavelength of visible light would produce a dark fringe at the same location? Assume that the range of visible wavelengths extends from 380 to 750 nm. Calculate the wavelength that fulfills the problem description. Clearly show all steps, starting from generalized equations. Explain your mathematical work in words.
