The source which emits a light wave with the same frequency, wavelength and phase or having a constant phase difference is known as a coherent source. A coherent source forms sustained interference patterns when the waves superimpose and the positions of maxima and minima are fixed.

There are two types of coherence, namely temporal coherence and spatial coherence. These two types are explained below.
Coherent sources of light are those sources which emit a light wave having the same frequency, wavelength and in the same phase, or they have a constant phase difference. A coherent source forms sustained interference patterns when the superimposition of wavesoccurs, and the positions of maxima and minima are fixed. Two independent sources are neve...
Coherent sources have the following characteristics: 1. The waves generated have a constant phase difference (they are in phase with each other). 2. The waves are of a single frequency. 3. The waves should have the same amplitude.
Finding a coherent source of light is sometimes difficult. Therefore, we can use different methods to produce such sources, and they are as follows: 1. By Dividing the Wavefront Wavefront is divided into several parts. We can use either different lenses, mirrors, and even prisms. Some of the techniques that can be followed are Young’s double-slit e...
Interference is a phenomenon in which two waves superimpose to form a resultant wave which has greater, lower or the same amplitude. Interference is of types – constructive and destructive. They result from the combination of waves that are interrelated or coherent with each other, either because they come from the same source or because they have ...
We need coherent sources of light mainly to observe the effects of interference. Coherent sources have the same phase, so the phase difference between the two sources remains constant. This is a necessary condition for observable and distinct interference. They help us identify the interference patterns that occur as a result of the change in phase...
Radiography is an old technique. Very recently, it took a new way that the coherence of a next-generation facility beam makes it possible in an easy way to break the usual barrier to absorption and to visualise phase features. The X-ray beam has, 1. A high spatial coherence, which means that the size and the divergence of the beam are very small. 2...

Sep 3, 2024 · Coherence, a fixed relationship between the phase of waves in a beam of radiation of a single frequency. Two beams of light are coherent when the phase difference between their waves is constant; they are noncoherent if there is a random or changing phase relationship.
