Different frequencies of visible light are perceived as different colors.
the range of visible light.
Different electromagnetic wavelengths/frequencies.
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
Ultraviolet light extends for quite a ways up the electromagnetic spectrum after visible violet ends. Its frequencies are higher. Wavelengths from 400nm to 50nm covering 4 groups of UV.
white light
infrared
Different frequencies of visible light are perceived as different colors.
Yes,visible light is used. Frequencies of blue and red absorbed effectively
A mixture of all the visible frequencies.
the range of visible light.
their wavelengths (frequencies)
Bonds in molecules absorb light, In black the bonds absorb a lot of visible light frequencies. As black only reflects few frequencies of visible light. it gains it black colour.
Violet
The cones in the retina of our eyes are sensitive to certain frequencies of light within the visible light spectrum (ROYGBIV). Light waves with longer wavelengths (within the visible range of frequencies) are perceived to be on the red, orange, yellow side of the spectrum, while higher frequencies/shorter wavelengths of light appear blue or violet.
Any black object or surface.
