STD 11 - 14. waves and sound — NEET STD 11 Science — Question

Gujarat BoardEnglish MediumSTD 11 ScienceNEETSTD 11 - 14. waves and sound4 Marks
MCQ
Coherent sources are characterized by the same
  • A
    Phase and phase velocity
  • B
    Wavelength, amplitude and phase velocity
  • C
    Wavelength, 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
