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.

Question

Which property of the wave does the value of two per second describe?
A.
intensity
B.
wavelength
C.
frequency
D.
amplitude

Answer 1

The value of two per second describes the C. frequency of the wave.

Frequency refers to the number of cycles (or pulses, in this case) that occur in a given time period, typically measured in hertz (Hz), where 1 Hz equals 1 cycle per second. In this scenario, the machine is producing compression waves at a frequency of 2 Hz (2 cycles per second).
