Unformatted text preview: δ p and δ s at three visible wave-lengths, using values for the index of refraction of water given in the table. Present these results in a table and explain the order of colors observed for the primary and secondary rainbow, from the inside to the outside of the bow. wavelength (nm) index of refraction 656.3 nm 1.331 589.3 nm 1.333 486.1 nm 1.337 (d) Use Fresnel’s equations to determine the fraction of incident in-tensity returned for the primary and secondary re f ections, in both S and P polarizations, at the extremal angles. Note that you will need to take into account three or four interfaces for each case. Based on the resulting four values, discuss the relative visibility of the primary and secondary bows, assuming that the sunlight is randomly polarized. 2...
