If temperature increases, the velocity of sound:
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains same
- D. Increases then decreases
Explanation
The velocity of sound is related to temperature as:v2 ∝ Tor v ∝ √THence, increasing temperature increases the velocity of sound.

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.
