If the distance between two consecutive crests of a wave is L, then the wavelength is given by:
AL/2
BL/4
C2L
DL
Answer & 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.
