The Speed of sound in air is 332 ms* at 0°C. What will be its value at 10°C?
Correct answer: B. 338.1 ms-1
- A. 332 ms-1
- B. 338.1 ms-1
- C. 332.61 ms-1
- D. 33.4 ms-1
Explanation
As the temperature increases by 1°C the speed of sound increases by 0.6 ms-1. Now if temperature increases by 10°C then,Speed of sound at 0°C =332ms-1Speed of sound at 10°C =332+0.61×10=338.1ms-1

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.
