Challenge Problems
Push your limits with advanced challenges
A string of length 2 m is fixed at both ends with a tension of 50 N. Calculate the wave speed if the mass per unit length is 0.25 kg/m.
💡 Hint: Remember to apply the wave speed formula correctly.
Explain how varying the tension in a string affects both wave speed and wave frequency, using the wave equation to support your answer.
💡 Hint: Use relationships between frequency, wavelength, and speed.
