Water Waves Approach an Aperture

question 26

Multiple Choice

Water waves approach an aperture. The resulting patterns are shown for two different cases, A and B, in which the wavelength and aperture size are varied. Which one of the following statements concerning these cases is true?

• A)Neither figure shows diffraction. In both cases, the wavelength is much smaller than the aperture.
• B)Diffraction occurs in A, but not in B because the wavelength in A is much smaller than the aperture.
• C)Diffraction occurs in B, but not in A because the wavelength in B is much smaller than the aperture.
• D)Both figures show diffraction. In both cases, the wavelengths are approximately the same size as the aperture.
• E)Diffraction occurs in B, but not in A because the wavelength in B is approximately the same size as the aperture.
