The term "mono" refers to a singular object or subject. The term "chrome" refers to colors. The term "monochrome" is a reference to a single color.
ie., if two lights are monochromatic that means they have same wavelength.
If two waves are monochromatic (having the same wavelength) and are of the same phase, these two waves are defined as coherent waves. Sources generating such waves are known as coherent sources.
a.k.a. "laser"
Laser is monochromatic (all the pieces of light have the same wavelength), and coherent (all the pieces of light are in phase).
An ordinary light contains more than one colour. A laser is monochromatic.
Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same wavelength.
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:
a.k.a. "laser"
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
That's monochromatic, coherent light. A well known source of such light is a laser.
monochromatic, coherent
A laser is a device to produce an intense monochromatic beam of coherent light.
Laser is monochromatic (all the pieces of light have the same wavelength), and coherent (all the pieces of light are in phase).
Monochromatic means "single-color". In contrast, white light is a mixture of many colors. In monochromatic light, each individual piece of light has the same frequency, and the same wavelength. Each piece of light does not necessarily have the same phase; if it does, the light is said to also be coherent.
Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.
