It means that all the parts of light are in phase - the crest of the waves for one photon coincide with the crests of the waves for another one.
Coherent light is light in which the electric and magnetic fields are perfectly synchronized and oscillate in phase with each other. This results in a single wavelength and direction, allowing the light waves to constructively interfere and produce a uniform, focused beam. Laser light is an example of coherent light.
is coherent, monochromatic, and concentrated in a narrow beam.
To produce two coherent sources of light, you can use a laser to create a beam of light with a single frequency and direction. By splitting the laser beam into two using a beamsplitter, you can then generate two coherent sources of light that have the same frequency and phase relationship.
Yes, LED light is coherent. It consists of photons that are in phase with each other, producing a single wavelength of light. This coherence is what allows LEDs to emit light with high efficiency and brightness.
Coherent light is light where all the electromagnetic waves oscillate in phase with one another. This results in a uniform, well-defined wavefront that enables interference patterns to be produced, such as those seen in lasers. Coherent light sources are characterized by their ability to produce a narrow beam with a consistent wavelength and direction.
Coherent light (like a laser) is a single frequency. Polychromatic light is, by definiation, multiple frequencies and cannot be coherent.
The name of the device that produces coherent light is LASER.

To generate an interference pattern the light needs to be coherent.
That's monochromatic, coherent light. A well known source of such light is a laser.
No. Laser light is coherent. Light bulb light is not.
interference of coherent light rays in a photographic emulsion. one set of coherent light rays take a direct path from the source to the emulsion, the other set of coherent light rays reflect off the object before arriving at the emulsion.
Yes, LED light is coherent. It consists of photons that are in phase with each other, producing a single wavelength of light. This coherence is what allows LEDs to emit light with high efficiency and brightness.
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
