Answer:
0.05s
Explanation:
frequency = speed / wavelength = 20/1 = 20Hz. Thus period = 1/f = 1/20 = 0.05 s
Frequency = speed / wavelength = 20/1 = 20Hz.
Thus period = 1/f = 1/20 = 0.05 s
Frequency is the number of waves that pass a fixed point in unit time.
The period of a wave is the time for a particle on a medium to make one complete vibrational cycle.
