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.
wave speed frequency 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:

• Frequency is measured in hertz (cycles per second), so the first blank is "frequency".
• Wavelength is measured in length units (centimeters here), so the second blank is "wavelength".
• Wave speed is measured in distance per time (centimeters per second here), so the third blank is "wave speed".

Answer:

Ell 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.
