If stretching force in a stretched wired is increased then its frequency of oscillation:
Correct answer: B. increases
- A. decreases
- B. increases
- C. remains same
- D. none of these
Explanation
f = (1/2L) * √ (T/m) Where: f = frequency of oscillation L = length of the wire T = tension in the wire m = linear density (mass per unit length) of the wire If the stretching force or tension (T) in the wire is increased while the other parameters remain constant, the frequency of oscillation (f) will increase. This means that the wire will vibrate at a higher frequency.

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.
