The wave has the highest frequency in option A.
What is frequency?
The frequency of a wave is the number of cycles completed by the wave in a given period of time. Frequency is measured in Hertz (Hz).
How to calculate frequency
The frequency of a wave is calculated as follows;
[tex]v = f \lambda\\\\f = \frac{v}{\lambda}[/tex]
where;
- f is the frequency
- v is the speed of the wave
- λ is the wavelength
From the given chart, in option A the wave completed more cycles in the given period of time.
Thus, the wave has the highest frequency in option A.
