Your friend uses a wire coil to model how a sound wave moves. What is an advantage to using the spring coil as a model.

• The model increases the complexity of the wave.

• The model shows the wave more quickly.

• The model can be measured much more accurately.

• the models can be observed from the classroom more easily.

Which is an electromagnetic wave?

• Light

• Sound

• Seismic (earthquake wave)

• water

Given the sound waves a formed by vibrating molecules, which statement is true?

• Sound waves travel fastest through space.

• Sound travels faster through water than through air.

• Sound travels at the same rate through all mediums.

• Sound travels faster through air than through water.

If a sound wave leaves a boulder and travels through the air, what would happen to the sound waves speed?

• The speed would decrease.

• The speed would increase.

• The speed would stay the same.
