Quiz -- Waves

1. What kind of waves can we produce with a slinky?

We can produce both transverse and longitudinal waves. In the picture below, (a) is a longitudinal wave also known as a compressional wave, while (b) is a transverse wave.

2. Is the following wave a transverse or longitudinal wave?

Transverse.

3. On the diagram above, identify the wavelength and the amplitude.

For wavelength, I can choose any point on the wave, and the next identical point on the wave. Here I choose 2 crests (high points).

4. Does a speaker produce a transverse or longitudinal wave?

The little diagram gives it away. The speaker is compressing the air. So it is longitudinal. Sound is a longitudinal wave. It requires a medium.

5. Does a tuning fork produce a transverse or longitudinal wave?

The little diagram gives it away. The tuning fork is compressing the air. So it is longitudinal. Sound is a longitudinal wave. It requires a medium.

6. On the diagram above, identify:

a. wavelength

b. rarefaction

c. compression
