Waves

Waves

1. Sound waves cannot travel through empty space or a vaccumm.

   • Sounds waves can travel through solids, liquids and gases.
     • Sounds waves are longitudinal waves. (The vibrations are in the same direction as the travel of direction)

2. The amplitude is the maximum height of the wave from its resting position.

   • The greater the amplitude, the louder the sound.
     • The wavelength is the distance between the crests (Tops) of two waves next to each other. (Or any other two identical point on waves next to each other)
       • The frequency is the number of waves per second.
         • The higher the frequency, the closer together the waves are and higher the pitch.
