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 else can I help you with?
Why laser beam is narrow straightwhere as light from tube light is blury?
A laser beam is a coherent light source that emits a narrow beam of light due to the alignment of its waves. In contrast, light from a tube light is incoherent and emits light in all directions, resulting in a blurry appearance. The difference in coherence and directionality between laser light and tube light accounts for their distinct characteristics.
How is visible light generated?
The simple answer is heat. If you heat anything enough it will start generating light. <><><> In addition to the above, materials that fluoresce will give off visible light when stimulated by various energies. See fluorescent light, Light Emitting Diodes, etc
Visible light contains various wave lengths what are the wavelengths in nanometers?
Visible light wavelengths range from approximately 400 to 700 nanometers. This corresponds to violet light at the shortest wavelengths and red light at the longest wavelengths in the visible spectrum.
The frequency of visible light falls between that of?
The frequency of visible light falls between ultraviolet and infrared light on the electromagnetic spectrum. It has wavelengths ranging from approximately 400 to 700 nanometers.
How do you produce a coherent wave?
A coherent wave is produced when two or more waves of the same frequency and with a constant phase difference combine together. This can be achieved using techniques such as interference or laser light generation. The waves effectively reinforce each other, resulting in a single, unified wave with consistent characteristics.
What is one difference between visible and non-visible light?
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
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 Give example.?
Coherent sources are sources of waves that have a constant phase difference between them. An example of coherent sources is two identical lasers emitting light waves with the same frequency and wavelength.
What is the identical light waves in a phase called?
Identical light waves in phase are called coherent light waves. Coherent waves have a constant phase difference between them, which allows for constructive interference and the formation of interference patterns.
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 the main difference between laser and ordinary white light?
The main difference is that laser light is coherent, meaning the light waves are aligned and moving in a single direction, while ordinary white light is non-coherent, with light waves traveling in random directions. Laser light is also monochromatic, meaning it consists of a single color, while white light contains a mixture of different colors.
What are coherent sources and conditions for it?
Coherent sources are sources that emit light waves with a constant phase relationship. Conditions for coherence include having the same frequency, wavelength, and waveform, as well as a constant phase difference between the sources. This coherence allows for interference effects to occur, resulting in patterns such as diffraction and interference fringes.
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.
