What is coherent light?
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.
A laser produces light that?
is coherent, monochromatic, and concentrated in a narrow beam.
How do you produce two coherent sources of light?
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.
What is a coherent light?
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.
What are the coherent light source?
Coherent light sources emit light waves that have a constant phase relationship with each other. This results in laser light being a common example of a coherent light source, as the waves are in sync and have a well-defined direction. Other examples include superluminescent diodes and some types of LEDs with special design characteristics.
Is poly chromatic light can be coherent?
Coherent light (like a laser) is a single frequency. Polychromatic light is, by definiation, multiple frequencies and cannot be coherent.
What is a device that produce coherent light?
The name of the device that produces coherent light is LASER.

Is it true or wrong that if the light rays are not coherent you would not be able to see interference?
To generate an interference pattern the light needs to be coherent.
Light of only one wavelength that travels with its crest and troughs aligned?
That's monochromatic, coherent light. A well known source of such light is a laser.
Can you put a LED inside a laser housing to focus it into a beam just like a laser diode would?
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
What will it take for the hologram to be created?
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.
What are coherence?
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:
