Chapter 35 327 Section 35.6 Huygen’s Principle *P35.28 (a) For the diagrams of contour lines and wave fronts and rays, see Figures (a) and (b) below. As the waves move to shallower water, the wave fronts bend to become more nearly parallel to the contour lines. (b) For the diagrams of contour lines and wave fronts and rays, see Figures (c) and (d) below. We suppose that the headlands are steep underwater, as they are above water. The rays are everywhere perpendicular to the wave fronts of the incoming refracting waves. As shown, the rays bend toward the headlands and deliver more energy per length at the headlands. (a) Contour lines (b) Wave fronts (c) Contour lines (d) Wave fronts and rays and rays FIG. P35.28 Section 35.7 Dispersion and Prisms P35.29 From Fig 35.21 n v = 1 470 . at 400 nm and n r = 1 458 . at 700 nm. Then 1 00 1 470 . sin . sin θ θ = v and 1 00 1 458 . sin
