Which type of energy is transferred by vibrational waves?
Nuclear
Chemical
Light
Sound
As air is pumped from a vacuum jar, the sound level of a ringing bell will decrease until it can no longer be heard. This happens because air must be present in the jar in order for
sound to be transferred
the rubber to seal the jar
electricity to flow through the wires
the bell clangor to vibrate
As a longitudinal wave moves to the right through a medium, the molecules of the medium move
in a circular motion
right to left
up and down
to the right
