Question
As a wave approaches the shore at an angle, it begins to refract, what causes this phenomena?
a. A part of the wave begins to slow down as it feels bottom, but the rest of the wave still moves quickly along. This causes bending
b. Typically as the waves approach the shore the wind also shifts due to friction with the land, The shift in wind direction also causes the waves to change direcdtion.
c. Very often there is a strong current near shore. As the waves move into this current they are bent or refracted.
d. Because of the increase in sediment in the water near shore, the water is a little denser. This change in density cause the wave to move a little slower creating a band or refraction.
Explanation / Answer
A
Differences in velocities of a wave at shallow water and deep water leads to refraction
