Question
In the given diagram, how many full waves have been shown?
- 4.5
- 3
- 4
- 3.5
Hint:
One wave is one cycle of a wave.
The correct answer is: 4.5
- 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 given diagram, there are 4 full cycle and 1 half cycle making it 4.5 cycle of a wave.
- So, the correct option is a.
