The frequency of sound is f and velocity is v, if frequency increases to 4f velocity will be:
Correct answer: A. v
- A. v
- B. 4v
- C. v/4
- D. 2v
Explanation
In a given medium sound speed depends on medium properties (elasticity, density), not frequency. If f increases, λ decreases such that v = fλ remains constant.

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.
