A wave has a wavelength of 4.9 m and a velocity of 9.2 m/s. The medium through which this wave is traveling is then heated to a greater temperature. What must be true about the frequency of this wave

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.
