which of the following has the greatest effect on the speed at which sound travels through a gas?
o the ability of electrons to travel through a medium
o the frequency of the wave
o the amplitude of the wave
o the proximity of the molecules of the medium

Explanation:

Sound is a mechanical wave that requires a medium to travel. The speed of sound in a gas is affected by the proximity of the gas molecules. When molecules are closer (higher density, like in a liquid - like state approximation in some gas conditions), sound can transfer energy (vibrations) more quickly. Amplitude affects loudness, frequency affects pitch, and electrons' ability to travel is related to electrical conductivity (not sound in gas).

Answer:

the proximity of the molecules of the medium
