Answer:
The number of oscillations completed by the wave in one second is 1.88 number of oscillations
Explanation:
Frequency of a wave is defined as the number of oscillations completed by a progressive wave in one second. It is expressed as the ratio of the velocity of the wave to its wavelength.
Mathematically, frequency = velocity/wavelength
Given velocity of the wave = 9.2m/s
wavelength = 4.9m
Frequency = 9.2/4.9
Frequency = 1.88Hertz
The value of frequency of the wave gotten means that the wave completed 1.88 oscillations in one second.
