wave_mechanics interference_and_superposition_of_waves Question 8
Coherent sources are characterized by the same frequency and phase
[KCET 1993]
Options:
A) Phase and phase velocity
B) Wavelength, amplitude and phase velocity
C) Wavelength, amplitude and frequency
D) Wavelength and phase
Show Answer
Answer:
Correct Answer: B
Solution:
Because in general phase velocity is not equal to 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
