What else can I help you with?
What kinds of lights can humans see?
Only in the 'visible light' spectrum.
What is the visible spectrum of white lights?
The visible spectrum is red, orange, yellow, green, blue, indigo, and violet. You can remember this by remembering ROY G. BIV as a man's name.
Where is the visible spectrum located?
On a sunny day, or in an inside room with the lights on, it is all around you.
What form of electromagnetic waves falls just after visible lights on the electromagnetic spectrum?
ultraviolet
The primary colors of visible lights are?
The primary colors of visible light are red, green, and blue. These colors can be combined in various ways to create all the other colors in the visible spectrum.
Do black lights exist and how do they work?
Yes, black lights exist. They emit ultraviolet (UV) light, which is not visible to the human eye. When UV light hits certain materials, they absorb the light and then re-emit it in a visible spectrum, creating a glowing effect that we can see. This is how black lights make objects appear to glow in the dark.
What is the spectrum of fluorescent light?
Fluorescent lights emit a spectrum of visible light that typically includes various wavelengths in the blue and green regions, with smaller amounts in the red and violet regions. They also emit ultraviolet light, which is not visible to the human eye but can cause fluorescence in certain materials.
If light of all visible wavelengths is combined the results appear to be what color?
If the lights from all visible wavelengths are combined, they appear to be a white color.
Why are black lights purple?
Black lights appear purple because they emit ultraviolet (UV) light, which is not visible to the human eye. However, some materials in the light bulb or coating on the bulb absorb the UV light and re-emit it as visible light, often in the purple range of the spectrum.
What is the spectra of fluorescent light?
The spectrum of fluorescent light consists of multiple narrow peaks of visible light, typically in the blue and green regions of the spectrum. Fluorescent lights emit a mix of ultraviolet light that excites phosphors coating the inside of the tube or bulb, which in turn re-emit visible light. The resulting spectrum can vary slightly depending on the specific phosphors used in the bulb.
Which basic property determines a colored lights placement on the spectrum of visible light?
Most of the spectrum charts that I have seen are listed in wavelengths, particularly nanometers (nm). Where 1 nm = 1x10^-9 m.
What color do red blue and green form when they all overlap?
red, blue and green color lights are combined to form visible light
