In stretched string, the speed of wave is independent of:
Correct answer: D. The point from where the string is plucked
- A. Tension
- B. Length
- C. Total mass of string
- D. The point from where the string is plucked
Explanation
The speed of a wave on a stretched string depends on the tension in the string and the mass per unit length. It is calculated using the formula v = √(T/μ), where T is the tension and μ is the mass per unit length. Thus, the wave speed is independent of the length of the string and the point from where the string is plucked. The point of plucking affects the initial conditions of the wave but not its speed. Therefore, both options B and D are correct.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
