The value of two pulses per second describes the frequency of the wave. Frequency is defined as the number of occurrences of a repeating event per unit of time, in this case, the number of waves produced per second.
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?
