What is the main difference between visible and coherent light?

First let us remove the word visible from this question and replace it with incoherent, as visible light can be either coherent or incoherent and coherent light can be either inside the visible spectrum or outside it.
- Incoherent light is random/unordered, e.g. wave phases different, shines in all directions, polychromatic.
- Coherent light is ordered in one or more ways, e.g. wave phases all synchronized, shines in one unidirectional collimated beam, monochromatic.
The difference between light in the visible spectrum or outside it is only whether humans can see it or not, there is no difference in the light itself other than wavelength.

What is the difference between a black light bulb and white light bulb?
Light is available in a variety of wavelengths depending on the emitter. Black light is in the ultraviolet range. White light is a mixture of frequencies in the visible range.
What is the name of the radiation between visible light and x rays?
ultraviolet light
Explain the difference between a light scanning and electron microscope?
A scanning electron microscope will scan the surface and an electron microscope looks inside.
What is the difference between diffraction and diffusion?
Diffraction is the spreading of waves that pass through a narrow opening or move past an obstacle ,whereas, interference is the phenomenon of redistribution of light in a medium as a result of light waves from two coherent sources.
Which part of the em spectrum is visible to the human eye?
Many particle physicists, radiation specialists, opticians and ophthalmologists have gotten togetherand named that part of the spectrum the "visible light" band.
What is the difference between infrared light and visible light ultraviolet light?
The difference is their wavelengths.
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:
What is the difference between the colours of visible light?
their wavelengths (frequencies)
What are coherent sources and conditions for it?
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.
What are coherent waves?
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:
What is the basic difference between ultravilolet visible light and infrared radiation?
Their wavelength.
What is the difference between visible light and gamma waves?
Gamma rays are of higher energy and much much shorter wavelength than visible light.
What is difference between visible and infrared light?
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
How do you make a distinguish between UV and VIS?
The only difference, between ultra violate light and visible light, is their frequencies, UV has higher frequency than visible and since wavelength x frequency = the speed of light (which is constant at 3x108 ms-1), therefore wavelength is higher in UV. UV light is also not visible, unlike visible light! so, in summery the difference is frequency and wave length.
What is the difference between the energy of ultra violet light and the energy visible light?
Ultraviolet light has a greater energy per photon.
What is the difference between light rays and heat radation?
Light rays are visible and have higher frequency compared to that of heat radiation Heat radiation is nothing but infra red which is not visible to human eyes. They have longer wavelength compared to that of visible light
What is the difference between light energy and radio wave energy?
Visible light and radio waves are both two types of the same radiation (electromagnetic waves). The difference is that visible light has a higher frequency; a higher energy per photon; and a smaller wavelength.
