How does sound travel?
a) Sound is a vibration that travels as a transverse wave.
b) Sound is a vibration that travels as a compression wave.
c) Sound is a vibration that travels as a transverse and compression wave.
d) Sound vibrates.
Sound waves transfer energy through a _____.
a) medium
b) wall
c) air
d) water
How does hitting a drum create a sound?
a) The drum skin vibrates; this compresses air particles; the air particles transfer as a compression wave through the air.
b) The drum skin compresses; the compression affects air particles; air particles travel to your ears.
c) The drum skin asks to be hits again; then makes a noise that travels through the air.
d) The drum skin vibrates; air particles move away; air particles travel to ear drums.
Sound travels fastest through
a) solids
b) liquids
c) gases
d)
