The diagram above illustrates a waveform. Determine the number of wavelengths in it
- 4
- 3\(\frac{1}{2}\)
-
2\(\frac{1}{2}\)
- 2
The correct answer is: C
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\(\frac{1}{2}\)
