Challenge Problems
Push your limits with challenges.
Question 1
A string of length 2 meters is fixed at both ends and under a tension of 50 N. Calculate the fundamental frequency of the string if its linear density is 0.01 kg/m.
π‘ Hint: Remember to calculate the wave speed first using T and ΞΌ.
Question 2
Explain how the frequency changes if the tension in the string is doubled while keeping the length constant.
π‘ Hint: Use the relationship between tension and wave speed.
