Solution: A water wave is a surface wave that travels through the ocean, caused by wind friction, while a tsunami is a series of ocean waves with extremely long wavelengths, caused by displacement of a large volume of water.
1.1 : What is the difference between a water wave and a tsunami? Solution: A water wave is a surface wave
Solution: Using the dispersion relation, we can calculate the wave speed: $c = \sqrt{\frac{g \lambda}{2 \pi} \tanh{\frac{2 \pi d}{\lambda}}} = \sqrt{\frac{9.81 \times 100}{2 \pi} \tanh{\frac{2 \pi \times 10}{100}}} = 9.85$ m/s. caused by wind friction
Solution: The reflection coefficient for a vertical wall is: $K_r = -1$. Solution: A water wave is a surface wave
4.1 : A wave with a wavelength of 50 m is incident on a vertical wall. What is the reflection coefficient?
