What is the primary factor that determines the speed of sound in a given medium?

The frequency of the sound waves

The ability of the particles in the medium to transmit the motions of the sound waves (correct)

The amplitude of the sound waves

The distance from the sound source

What is the relationship between the pitch of a sound and the frequency of the sound wave?

Pitch is determined by the intensity of the sound wave

Pitch is independent of the frequency of the sound wave

A high-pitched sound corresponds to a high frequency sound wave (correct)

A high-pitched sound corresponds to a low frequency sound wave
