Question
Summarizing from the material above, we end up with the following table: Lab 7 Activities From the above material on changes to a wave entering shallow water, what happens to the wavelength of a wave as it enters shallow water? ______________ What happens to the period of a wave as it enter shallow water? ___________ Between reflection, refraction, and diffraction, which process is the most likely to cause sand deposition at a beach flanked by rocky points? _______________ How does this promote sand deposition on the beaches? _____________
Explanation / Answer
1) waves entering shallow water have low wavelength and hence they travel at low speeds
2) the wave period of wave entering shallow water remains constant
