MCQ
Coherent sources are those sources for which
- APhase difference remain constant
- BFrequency remains constant
- ✓Both phase difference and frequency remains constant
- DNone of these
✓
Answer
Correct option: C.
Both phase difference and frequency remains constant
c
A coherent source continuously emits light with a constant frequency and wavelength. Also, the phase difference in the light waves are always constant. If these properties are satisfied, only then a source is called coherent.
