The value of two pulses per second describes the frequency of the wave. Frequency is the number of cycles or waves that occur in a given time period, typically expressed in hertz (Hz), where 1 Hz equals one cycle per second. In this case, the frequency is 2 Hz.
A machine produces compression waves in a spring that is 120 cm long by pulsing twice every second. The back and forth movement of the pulse creates compressed sections of the spring that are 30 cm apart and travel toward the other end of the spring. Which property of the wave does the value of two per second describe? (1 point) Responses frequency frequency wavelength wavelength amplitude amplitude intensity.b
