Practice Question

1.Is a sound wave longitudinal or transverse?

Longitudinal

2. State the definition of a  longitudinal wave.

A longitudinal wave will vibrate along the direction in which it transfers energy. 

3. A sound wave is a series of compressions and rarefactions.

4. A compression is a high pressure region

5. A rarefaction is a low pressure region.

6. What do sound waves need to travel through?

Medium

7. State what sound waves cannot travel through

Vacuum

8. Explain how a sound wave will affect the particles of a solid as it passes through the solid.

When a sound wave passes through a solid such as glass, it will cause vibrations within the solid.

The solid particles that receive the sound wave will vibrate at the same frequency as the sound wave.
