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 do colors have to do with visible light?
The visible light contains wave lenghts from 200nm to 800nm. 200 nm corresponds with the violet/blue colour and 800nm and around corresponds with red colour. Above 800nm wave lenght of the light is called infrared and below 200nm - ultraviolet. The shortest the lenght, the higher the energy. After ultraviolet we have radio waves, micro waves, X-rays, etc.
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.
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 is the difference between the colours of visible light?
their wavelengths (frequencies)
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.
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 a black light and a regular light bulb?
A black light emits ultraviolet (UV) light, which is not visible to the human eye but can cause certain materials to fluoresce. A regular light bulb emits visible light that illuminates the surrounding area.
What is the difference between laser and visible light In terms of wavelength wave frequency and health hazards.?
because that's the way it is....
What is the comparison between visible light and ultra violet light?
You can see visible light but not ultra violet 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.
