The speed of sound is independent of changes in:
Correct answer: A. Pressure
- A. Pressure
- B. Temperature
- C. Density
- D. Humidity
Explanation
The speed of sound is primarily dependent on the properties of the medium through which it travels, such as temperature and density. However, it is largely independent of changes in pressure. Therefore, the speed of sound remains relatively constant even if there are changes in pressure.

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.
