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?
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
