Why do light from two different sources doesn't form coherent sources?

Description : Why do light from two different sources doesn't form coherent sources?

Last Answer : Why would they? It makes more sense for them to be different. There is not an equal amount of energy in the production of the light, they are probably different colors, and if they are not in an identical place to begin with, they’ll be out of phase.

The Laser is a beam of radiations which are – (1) Non-coherent and monochromatic (2) Coherent and monochromatic (3) Non-coherent and non-monochromatic (4) Coherent and non-monochromatic

Description : The Laser is a beam of radiations which are – (1) Non-coherent and monochromatic (2) Coherent and monochromatic (3) Non-coherent and non-monochromatic (4) Coherent and non-monochromatic

Last Answer : (2) Coherent and monochromatic Explanation: Laser, an acronym for Light Amplification by Stimulated Emission of Radiation, creates a radiation beam that is coherent (in-phase). In a coherent light ... results in a radiation beam of great intensity. It normally produces only one or two wavelengths.

Laser is a device to produce - (1) a beam of white light (2) coherent light (3) microwaves (4) X-rays

Description : Laser is a device to produce - (1) a beam of white light (2) coherent light (3) microwaves (4) X-rays

Last Answer : (2) coherent light Explanation: In physics, two wave sources are perfectly coherent if they have a constant phase difference and the same frequency, and the same waveform. Coherence is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference.
