The first diagram represents the movement of sound from music playing through a speaker to a person’s ear.

The second diagram represents the movement of light from a source to an object and then to an observer.

Which statement best explains which type of energy shown needs a medium through which to travel?

• Sound needs to travel through a medium because the energy is produced by a speaker.

• Light needs to travel through a medium because it involves the movement of light rays.

• Sound needs to travel through a medium because it involves the movement of particles.

• Light needs to travel through a medium because the energy is moved in two directions.
