Figure 28. — Aerial photograph showing refraction of waves at Purisima Point, Calif. The waves shown here are from winds blowing 

 directly on to the coast. Note that the waves in the upper portion of the picture are almost parallel to the shore line as a result 

 of refraction. The deep water wave length is about 600 feet,- the wave height 6 feet,- and the breaker height 9 feet.
