Science Buddies: "Ask an Expert"

with white being all of the wavelengths combined, is there a "visual" for its "wavelength"? is it like a bundle of all the visible light wavelengths, could it be what/where visible light is on the EM spectrum, or is it impossible to imagine? (or another possibility)

Hi galaxyfish,

Yes, white is just all wavelengths combined. There isn't really another possibility for any other visible light, as any length less than 400 micrometers is UV light(the sun) and any length above 700 micrometers is infrared, where the energy is too low to be visible. The color white is also 255,255,255 on the RGB scale which maxes out the amount of red, green, and blue you can put into a color. This is essentially as you said it, just a compilation of all visual light wavelengths.
