Question

One yellow wave passes this
point each second, so the
frequency is

Answer 1

Step-by-step explanation:

The frequency of a wave is the number of wave cycles that pass a given point per unit of time. In this case, we are told that one yellow wave passes a given point each second. Therefore, the frequency of the wave is 1 wave/second, or simply 1 Hz (Hertz), since Hz is the unit of measurement for frequency, and it represents the number of cycles per second.
