The distance between two successive trough points of a wave is
A
two wavelength
B
a wavelength
C
one third wavelength
D
half wavelength
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
The distance between two successive troughs of a wave is equal to one wavelength (λ)
One wavelength (λ) is defined as the distance between two successive points in the same phase (crest to crest or trough to trough).
