• They are all forms of energy carried in waves.

• They are all forms of energy that do not require a medium.

• They are all forms of energy that can only travel through air.

Which of the following is NOT an example of a wave?

How do molecules in a wave pass energy?

• By moving from one place to another

• By passing energy to neighbor molecules

• By absorbing energy from the wave

• By producing vibrations

What causes waves to be produced?

• Absorption of energy by a medium

• Energy being carried from place to place

• The movement of matter

Under what condition will waves continue to travel?

• As long as there is matter to carry
