Think about the standard forms of differential equations.
Question 5.
Given a wave with a period of 4 seconds and a wavelength of 20 meters, find the wave speed and discuss its relationship with the velocity potential.
Show hintHide hint
Use the relationship between speed, wavelength, and period to derive the answer.
Question 6.
Derive the expression of the velocity potential phi considering specific boundary conditions you've learned.
Show hintHide hint
Apply each boundary condition sequentially to simplify the resulting terms.
