Reflection and Absorption of Sound Waves

Sound waves moves perpendicular to the disturbance

Sound waves moves in the same directions as the disturbance

Sound waves move through the vacuum of space

Sound waves must have a medium through which to travel

liquid

gas

solid

plasma

waves transfer matter not energy

waves transfer both matter and energy

waves transfer energy not matter

waves transfer neither matter nor energy

vibrations

magnetic field

low pressure

Increase the wavelength of the wave

Decrease the amplitude of the wave

Decrease the energy of the wave

Increase the frequency of the wave
