The speed of the waves in the string in terms of the tension F and mass per unit length (m) of the string is given by:
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The speed "v" of the waves in the string depends upon the tension "F" and mass per unit length of the string "m". the speed "v" of the wave is given by:v = √ (F/ m)

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.
