Light sources which emit light waves of same wavelength (or frequency) having either zero or a constant originating phase difference are called coherent sources of light.

What are coherent sources of light?
Share
Coherent sources of light emit waves with a constant phase difference, the same frequency, and wavelength. These sources maintain a stable phase relationship over time, enabling the formation of clear and stable interference patterns. They are essential for experiments like Young’s double-slit.
