Under identical conditions of pressure and density, the speed of sound is highest in:
Correct answer: A. Monoatomic gas
- A. Monoatomic gas
- B. Diatomic gas
- C. Triatomic gas
- D. Polyatomic gas
Explanation
Monoatomic gases have the highest speed of sound under identical conditions of pressure and density. This is because the speed of sound is related to the mass of the gas particles and their ability to transmit sound waves, and monoatomic gases have the lowest molecular mass, resulting in the highest

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.
