Challenge Problems
Push your limits with challenges.
Question 1
A wave travels at a water depth of 10 meters. How would the dispersion relationship change if the depth is increased to 30 meters? Explain.
💡 Hint: Consider how the function tanh behaves with increasing values of k and d.
Question 2
Given a period of a wave is 4 seconds and using the dispersion equation, derive the wavelength required for a given water depth of 5m.
💡 Hint: First, calculate k then backtrack to find the wavelength.
