It does not have a single wavelength; it is a mixture of colors with different wavelengths. For example, if you shine red, green and blue lights of similar saturation strength together (so that one doesn't overpower the others) the result will appear white. There's an old saying that black is the absence of color, while white is the presence of all colors. Which is why another term for visible light is 'white light'.

What colour of white light is deviated most?
Red , because it has largest wavelength
What colors are associated with wavelength?
Of the colors visible to humans, red light has the lowest wavelength. Violet light and white light have the highest wavelengths.
Why white light of sun cannot considered pure and uniform?
The white light of the sun cannot be considered pure and uniform because they have different wavelength in different times.
What is a light wave?
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
What is the length of an ultraviolet wavelength compared to an x-ray wavelength?
The wavelength of the x-ray is shorter.
What is the difference between white and colorless?
white absorbs every wavelength ......... but colourless transmit evry wavelength
What colour of white light is deviated most?
Red , because it has largest wavelength
What colors are associated with wavelength?
Of the colors visible to humans, red light has the lowest wavelength. Violet light and white light have the highest wavelengths.
Do you get hotter in black clothes then white when it is hot?
Yes, because black clothes absorbs every wavelength of light, while the white clothes reflects every wavelength of light, thus black clothes absorbing the most heat.
For a substance to appear white what must happen to all wavelength of light?
must be reflected
What wavelength does white light from the sun have?
Visable light, Infra red and uv rays.
Why does a white piece of paper appear white in white light red in red light blue in blue light and so on?
White surface reflects all wavelengths of visible light spectrum (ie. white color is a mixture of all the other colors). If the light that falls on the surface has one specific wavelength, only that wavelength occurs in the light reflected.
Why are towers painted ir orange and white?
Towers are painted in orange and white rather than red and white..... as the red colour has the highest wavelength but it's specified for the DANGER sign...hence the next longest wavelength colour 'orange' has been chosen....therefore, to increase the visibility of the tower.

What is monochromatic source?
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
What is the difference between yellow light and white light?
White light is a mixture of all the wavelengths of the visible spectrum. Visible light ranges from approximately 400 to 800 nm in wavelength. Wavelength of yellow light is565-590 nm.We perceive electromagnetic radiation with a wavelength between 565 and 590 x 10-9 m as yellow light.
Why can a white light be split up?
"White" is not a single wavelength of light. It is at least three wavelengths of light to which our eyes are attuned. Matter treats each wavelength differently, so it is possible / likely that a given transparent material will separate the individual colors differently with refraction.
