Practice identifying and comparing frequency, amplitude, and wavelength in different kinds of waves.
Read each problem carefully. Use complete sentences when asked to explain your thinking.

- 4
A wave on a rope has very tall crests and deep troughs. Describe its amplitude.
- 5
Two sound waves are compared. Wave A repeats 10 times in one second, and Wave B repeats 4 times in one second. Which wave has the greater frequency?
- 6
Two water waves travel the same distance. Wave X has crests that are closer together than Wave Y. Which wave has the shorter wavelength?
- 7
A student says that increasing amplitude changes how much energy a wave carries. Is the student correct? Explain.
- 8
If the frequency of a wave increases while the wave speed stays the same, what happens to its wavelength?
- 9
A wave has a wavelength of 2 meters. This means the distance from one crest to the next crest is how far?
- 10
Compare these two waves: Wave 1 has a large amplitude and low frequency. Wave 2 has a small amplitude and high frequency. Describe one difference between them.
- 11
A tuning fork produces a sound wave with a higher frequency than another tuning fork. How will the sound usually be perceived?
- 12
Explain how frequency, amplitude, and wavelength are different from one another.
