The diagram above illustrates a waveform. Determine the number of wavelengths in it
4
3\(\frac{1}{2}\)
2\(\frac{1}{2}\)
2
Explanation
Number of wavelengths = Number of oscillations
Number of wavelengths = \(\frac{1}{4} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} +\frac{1}{4}\) = 2\(\frac{1}{2}\)
