Coherent source:
- Two or more sources are said to be coherent if they emit waves that have the same wavelength (or frequency) and amplitude and which maintain a constant phase difference.
- Being a Coherent source is an ideal property of waves that enables a stationary (i.e. spatially constant and temporally) interference.
EXPLANATION:
- If two sources have an equal wavelength and constant phase differences i.e., the phase difference between two waves does not change with respect to time.
- They are coherent sources of waves. Therefore option 3 is correct.
