Question

another property of longitudinal waves is wave speed. it is the distance a wave travels in a certain amount of time.
wave speed is a different property than frequency or wavelength.

• frequency is the number of wave cycles that pass a certain point in a certain amount of time.
• wavelength is the length of one wave cycle.

complete the sentence.
frequency wave speed wavelength
eli creates a wave in the spring toy. the wave has a of 3 hertz (cycles per second), a of 10 centimeters, and a of 30 centimeters per second.

Explanation:

Match each term to its definition:

1. Frequency is measured in hertz (cycles per second).
2. Wavelength is a length measurement (centimeters).
3. Wave speed is distance over time (centimeters per second), and also verifies with the formula $v = f\lambda$: $3 \text{ Hz} \times 10 \text{ cm} = 30 \text{ cm/s}$.

Answer:

Eli creates a wave in the spring toy. The wave has a frequency of 3 hertz (cycles per second), a wavelength of 10 centimeters, and a wave speed of 30 centimeters per second.
