27.4 Exercise 1

Avg difficulty 2.5

Which of the following cannot be a possible outcome of passing white light through several evenly spaced parallel slits?

  1. The central maximum will be white but the higher-order maxima will disperse into a rainbow of colors.
  2. The central maximum and higher-order maxima will be of equal widths.
  3. The lower wavelength components of light will have less diffraction compared to higher wavelength components for all maxima except the central one.
  4. None of the above.
