What is a wave? Use the terms wavelength and frequency in your definition. [Select all that apply.) C] The number of crests that move past a given location for each unit of time corresponds to the frequency of the wave. C] The distance between crests [or troughs) of the wave is the frequency. C] A wave is a repeating disturbance that travels outward. C] The distance between crests {or troughs) of the wave is the wavelength. C] The number of crests that move past a given location for each unit of time corresponds to the wavelength of the wave. C] A wave is a repeating disturbance that only travels parallel to the source
