Waves sounds and mirror 8th grade

What is a wave according to the provided learning material?

• A disturbance that repeats irregularly in space and time and transports matter.

• A pattern that occurs in water when an object is dropped into it.

• A disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transport of matter.

• A movement of air that creates sound.
