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.
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:

The problem is about wave properties. Frequency is defined as the number of wave cycles per unit time (hertz). Wavelength is the length of one wave cycle (centimeters). Wave speed is the distance a wave travels per unit time (centimeters per second).

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.
