Web26 jul. 2024 · Coherent light is electromagnetic radiation that has a certain wavelength. So it is always a single -colour light, since the wavelength determines the colour. In … Web28 okt. 2011 · Coherent Light Coherence is a property of light that enables waves to form temporary or stationary interference patterns. Coherence is defined to two waves. If two waves are monochromatic (having the same wavelength) and are of the same phase, these two waves are defined as coherent waves.

Web27 feb. 2024 · The waves are of a single frequency and wavelength. The waves should have the same amplitude. EXPLANATION: Coherent sources of light are those sources that emit a light wave having the same frequency, wavelength and in the same phase or they have a constant phase difference. Hence, option 3 is correct. WebCoherence light indicates the zero phase difference light and has the same frequency whereas incoherent light indicates different phase and random frequencies of light …
