Question

Which of the following has the greatest effect on the speed at which sound travels through a gas?A. the ability of electrons to travel through a mediumB. the frequency of the waveC. the amplitude of the waveD. the proximity of the molecules of the medium

Answer 1

The speed of the wave mainly impacted by the properties of the medium.

Thus, the frequency, amplitude of the wave does not cause any impant on the speed of the sound wave traveling through the gas.

The sound wave is the transmission of the energy through the medium, thus, it does not depends upon the ability of electrons to travel through a medium.

Thus, the proximity of the molecules in the medium or the density of the medium effect the speed of the sound wave.

Hence, option D is the correct answer.
