Question

what is a wave? use the terms wavelength and frequency in your definition. (select all that apply.) the number of crests that move past a given location for each unit of time corresponds to the frequency of the wave. a wave is a repeating disturbance that travels outward. the distance between crests (or troughs) of the wave is the wavelength. the distance between crests (or troughs) of the wave is the frequency. a wave is a repeating disturbance that only travels parallel to the source. the number of crests that move past a given location for each unit of time corresponds to the wavelength of the wave.

Explanation:

A wave is a repeating disturbance that travels outward. Wavelength is the distance between crests (or troughs) of the wave. Frequency is the number of crests that move past a given location for each unit of time.

Answer:

A wave is a repeating disturbance that travels outward.
The distance between crests (or troughs) of the wave is the wavelength.
The number of crests that move past a given location for each unit of time corresponds to the frequency of the wave.
