MCQ
What is the phase difference between two successive crests in the wave
- A$\pi$
- B$\pi /2$
- ✓$2 \pi$
- D$4 \pi$
✓
Answer
Correct option: C.
$2 \pi$
c
(c) Since distance between two consecutive crests is $\lambda$, so
(c) Since distance between two consecutive crests is $\lambda$, so
$\phi = \frac{{2\pi }}{\lambda } \times \lambda = 2\pi .$
