Challenge Problems
Push your limits with challenges.
Question 1
Calculate the wave speed in a channel with varying depths of 0.5 m and 3 m under standard gravity. Then analyze how this affects the wave propagation.
💡 Hint: Use the relationship c = √(gy) for solutions.
Question 2
Consider a channel where the depth suddenly changes from 2 m to 5 m. If the initial wave speed was 3 m/s, calculate the new wave speed and discuss its implications.
💡 Hint: Reapply the wave speed formula to assess the impact of changing depths.
