By increasing the temperature of medium about 1°C, the speed of sound is increased up to
Correct answer: C. 0.61 ms-1
- A. 0.41 ms-1
- B. 0.51 ms-1
- C. 0.61 ms-1
- D. 0.71 ms-1
Explanation
For every 1°C increase in temperature, the speed of sound in air increases by about 0.6 m/s.

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.
