In Figure 38.4, assume the slit is in a barrier that is opaque to x-rays as well as to visible light. The photograph in Figure 38.4b shows the diffraction pattern produced with visible light. What will happen if the experiment is repeated with x-rays as the incoming wave and with no other changes? (a) The diffraction pattern is similar. (b) There is no noticeable diffraction pattern but rather a projected shadow of high intensity on the screen, having the same width as the slit. (c) The central maximum is much wider, and the minima occur at larger angles than with visible light. (d) No x-rays reach the screen.

Solution Summary: The author explains that the diftion pattern cannot be similar as there is a large difference of wavelength between the visible light and x-rays.

You are conducting a single-slit diffraction experiment with light of wavelength l. What appears, on a distant viewing screen, at a point at which the top and bottom rays through the slit have a path length difference equal to (a) 5l and (b) 4.5l?
In a single-slit diffraction experiment, monochromatic light of wavelength 505 nm is passed through a slit 0.320 mm wide, and the diffraction pattern is observed on a screen 7.14 m from the slit. The intensity at the center of the pattern is ?0. What is the ratio of the intensity at the center of the pattern to the intensity at a point 3.09 mm from the center of the diffraction pattern (?/?0)?
A double-slit experiment has a slit separation distance of 0.08 mm. If the bright interference fringes are to be spaced 5 mm apart on the screen when the slits are illuminated with a laser of wavelength 633 nm, what should be the distance to the screen from the slits?
a) 0.42 m
b) 0.63 m
c) 0.77 m
d) 0.81 m
e) 0.92 m
