A wave travels with speed c = 3 m/s over a 2-meter deep pond. If the wave speed increases by 1 m/s, what is the new depth assuming constant gravity?
💡 Hint: Root values apply to both situations. Set their equations equal and solve.
In a channel, fluid depth is increased from 1.5m to 3.0m. Calculate the change in wave speed assuming gravity remains constant.
💡 Hint: Utilize the wave speed formula and substitute values in.
