Question

Coherent sources are characterized by the same

[KCET 1993]

• A. Phase and phase velocity
• B. Wavelength, amplitude and phase velocity
• C. Wavelength, amplitude and frequency
• D. Wavelength and phase

Answer 1

Answer: (B), (C)

The correct options are
B

Wavelength, amplitude and phase velocity

C

Wavelength, amplitude and frequency

Because in general phase velocity = wave velocity. But in case of complex waves (many waves together) phase velocity may not be equal to wave velocity.
