Challenge Problems
Push your limits with challenges.
Question 1
A string is stretched with a tension of 80 N and has a mass per unit length of 0.04 kg/m. Calculate the wave speed and the fundamental frequency if the string length is 1 m.
π‘ Hint: Calculate wave speed first, then use it to find frequency.
Question 2
For a uniform string under tension varying from 10 N to 80 N, analyze how wave speed varies and describe the relationship.
π‘ Hint: Refer back to the formulas we've learned to link tension to wave speed.
