In what way are sound waves similar to light waves? A. Sound waves and light waves transmit energy without transporting matter.
B. Sound waves and light waves create energy by vibrating particles.
C. Sound waves and light waves absorb particles when they pass through solid matter,
D. Sound waves and light waves travel the fastest through empty space.

A) Sound waves and light waves transmit energy without transporting matter.

Explanation:

A. Wave – a repeating disturbance or movement that transfers energy through matter or space.

1. Molecules pass energy on to neighboring molecules.

2. Waves carry energy without transporting matter.

3. All waves are produced by something that vibrates.

4. Medium – a material through which a wave travels.

a. May be solid, liquid, or gas.

b. Not all waves need a medium to travel through.

    Example: Light waves

In a wave phenomenon, energy can move from one location to another, yet the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter.

Waves are seen to move through an ocean or lake; yet the water always returns to its rest position. Energy is transported through the medium, yet the water molecules are not transported. Proof of this is the fact that there is still water in the middle of the ocean. The water has not moved from the middle of the ocean to the shore. If we were to observe a gull or duck at rest on the water, it would merely bob up-and-down in a somewhat circular fashion as the disturbance moves through the water. The gull or duck always returns to its original position. The gull or duck is not transported to the shore because the water on which it rests is not transported to the shore. In a water wave, energy is transported without the transport of water.

The same thing can be said about a stadium wave. In a stadium wave, the fans do not get out of their seats and walk around the stadium. We all recognize that it would be silly (and embarrassing) for any fan to even contemplate such a thought. In a stadium wave, each fan rises up and returns to the original seat. The disturbance moves through the stadium, yet the fans are not transported. Waves involve the transport of energy without the transport of matter.
