What is meant by coherent sources of light? View Solution. Q 3. Assertion :Only coherent light sources produce sustained interference. Reason: Coherent light sources emit lights of same wavelength and with a constant phase difference.
Coherent Waves. If the potential difference between two waves is zero or is constant w.r.t time, then the two ways are said to be coherent. Non-coherent Waves. The waves are non-coherent if the potential difference between the two ways keeps on changing. Lightbulb, study lamp are the examples of the coherent waves.
Coherent sources are those which have exactly the same frequency and are in this same phase or have a zero or constant difference. Conditions: (i) The sources should be monochromatic and originating from common single source. (ii) The amplitudes of the waves should be equal. (a) Condition for formation of bright and dark fringes.
In Young's double-slit experiment, the separation between two coherent sources S 1 and S 2 is d and the distance between the source and screen is D. In the interference pattern, it is found that exactly in front of one slit, there occurs a minimum.

What are the coherent sources of light and why do we need coherent sources for the production of interference pattern ? View Solution. Q 3. Assertion :Only coherent light sources produce sustained interference. Reason: Coherent light sources emit lights of same wavelength and with a constant phase difference. View Solution.
The SI Units list comprises a coherent system of units of measurement which begins with the seven base units. The seven base units are second, metre, kilogram, ampere, Kelvin, mole, and candela. The SI unit full form is the International System of Units.
Define the term 'coherent sources' which are required to produce interference pattern in Young's double slit experiment.
7. Coherent. The messages that you send should be logical and that is why coherent communication is important. The message involves certain ideas and thoughts and thus when they are coherent than only they are able to convey the main idea of the message. All the points that you have mentioned should be relevant to the topic and connected.
