To analyze single-slit diffraction, what new assumption not made in the Young double-slit experiment must be made?
  1.Each portion of the slit acts as a source of light waves.
  2.The light's wavelength is at the red end of the spectrum.
  3.Interference effects can be ignored.
  4.The distance between the slit and the screen is much greater than the wavelength of the light.

Question 2

The bright light at the center of a shadow cast by a penny
  1.supports the hypothesis that light can be viewed as rays traveling in straight lines.
  2.results from the re-reflection of the diffraction pattern cast by the penny.
  3.is the result of the penny's shininess; it acts like a mirror providing a second source to create an interference pattern.
  4.is the central maxima of the interference pattern caused by the diffraction effects around the penny.
