Question
In the given diagram, how many full waves have been shown?
- 2.5
- 2
- 3
- 3.5
Hint:
Wave wavelength is defined as the length of a complete wave cycle.
The correct answer is: 2.5
- The wavelength of a wave is called the length of one complete wave cycle.
- Therefore, one wavelength is defined as one cycle of a wave.
- In the given diagram, there are 2 full waves and 1 half wave, a total of 2.5 waves are given.
- So, the correct option is a.
