This property of light is observed when atoms de-excite from their excited state simultaneously. The temporal coherence is explained by the lifetime of atoms in their excited state.
The temporal coherence has explained the monochromaticity of the light source. It is a measure of the correlation of light waves phase at different directions of propagation. It is a type of coherence depending upon the time. It is also known as longitudinal coherence. There are two types of coherence depending on the position and time and are given by:įor understanding coherent light meaning with further details, let us start with the discussion of types of coherence in detail. Now, what is coherence? The coherence of light gives the correlation between any two points of light waves which have a constant phase with respect to time is known as the coherence of light, this property is known as coherence and this is the coherence definition Physics. One of the important parameters associated with the brightness of any light source is its coherence ability. In physics when we are discussing concepts of optics, the behavior of light plays an important role. Now let us have a look at coherence physics or coherent meaning in physics. The laser is a highly coherent light source. LASER light is considered to be the best example of the coherent light source. The property of any light source to measure a definite correlation between any two points with the same frequency and amplitude is known as the coherence of light and the light source is known as the coherent light source. When two or more light waves are traveling together in such a way that their phase difference with respect to time is constant, then such waves are known as the coherent waves.
