MCQ
Coherent sources are characterized by the same
- APhase and phase velocity
- BWavelength, amplitude and phase velocity
- CWavelength, amplitude and frequency
- ✓Both $(b)$ and $(c)$
✓
Answer
Correct option: D.
Both $(b)$ and $(c)$
d
(d) Because in general phase velocity = wave velocity. But in case of complex waves (many waves together) phase velocity $ \ne $ wave velocity.
$\therefore $ If two waves have same $\lambda ,v;$ then they have same frequency too
