  1.there is a secondary rainbow with the spectral colors reversed from the primary rainbow.
  2.light has properties of both waves and particles.
  3.all points on a wave front can be taken as point sources of secondary spherical wavelets which construct the new position of the wave front as time passes.
  4.rainbows are a result of dispersion.

Question 2
