If the distance between two consecutive crests of a wave is L, then the wavelength is given by:
- L/2
- L/4
- 2L
- L
Show answer and solution
Correct answer: D. L
1. Wavelength is the distance covered in one complete wave cycle.
2. The distance between two successive crests is exactly one full cycle.
3. Therefore the wavelength equals L.
