Solution
Correct Answer:
√(T/μ)
The speed of a transverse wave on a stretched string is determined by the properties of the string: v=μT
- T: Tension in the string (higher tension increases the restoring force, speeding up the wave).
- μ: Linear mass density (mass per unit length, M/L). Higher density (heavier string) increases inertia, slowing down the wave. Musical instruments are tuned by adjusting T or selecting strings of specific μ.
This easy difficulty physics question is from the chapter oscillations and waves, covering the topic of wave speed string. It appeared in the 2025 exam.
