Wavelength (λ): the distance the wave travels during one cycle. What are the units?

The distance travelled by a pulse per unit of time is called:A Time period B Pulse speed C Wavelength D Frequency

In the equation C = λν, what does the λ represent?    a. frequency     b. wavelength     c. speed of light      d. nuGroup of answer choicesACBD

Wavelength is the between one point on a wave and the nearest point just like it.
