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.
30 centimeters per second 2 hertz 1.5 centimeters
eli creates a wave in the spring toy. the wave has a frequency of (cycles per second), a wavelength of , and a wave speed of

Explanation:

Step1: Recall the definitions

Frequency is cycles per second. From the given options, 2 hertz (since 1 hertz = 1 cycle per second) is the frequency.

Step2: Recall wavelength definition

Wavelength is the length of one wave cycle. So 15 centimeters is the wavelength.

Step3: Recall wave - speed definition

Wave speed is distance traveled per time. So 30 centimeters per second is the wave speed.

Answer:

Eli creates a wave in the spring toy. The wave has a frequency of 2 hertz (cycles per second), a wavelength of 15 centimeters, and a wave speed of 30 centimeters per second.
