The speed of sound in an ideal gas depends upon:
Correct answer: C. Temperature and density
- A. Ice
- B. Frequency and fog
- C. Temperature and density
- D. Density and amplitude
Explanation
The correct statement is C. Temperature and density.The speed of sound in an ideal gas depends on both temperature and density. In fact, the speed of sound is given by the equation:Speed of Sound (v) = √(γ * (Pressure / Density)where γ is the adiabatic index or ratio of specific heats, which depends on the gas, and both temperature and density are involved in this equation.

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.
