Sound
Sound is a form of energy produced by vibrations. Sound needs a medium to travel, it can't travel through a vacuum.
- Speed (V) = distance (s)/time(t)
- Loudness depends on the amplitude of the sound wave. The greater the amplitude of the wave the louder the sound.
Sound waves are longitudinal waves, made by particles vibrating
The pitch of a note is how high the note is. The pitch depends on the frequency and the wavelength of the wave - the higher the frequency, the higher the note. The shorter the wavelength of the wave, the higher the note.
