How is wavelength related to color?

Answer 1

Lightwaves have both wavelength and frequency. Even though the wavelengths are different, all light travels at the same constant speed (in a given medium) , about 186,000 miles per second (in air) .

Color Wavelength (nm) Frequency (THz)

Red 780 - 622 384 - 482

Orange 622 - 597 482 - 503

Yellow 597 - 577 503 - 520

Green 577 - 492 520 - 610

Blue 492 - 455 610 - 659

Violet 455 - 390 659 - 769

As you can see, the longer the wavelength in nanometers, the lower the frequency in terahertz and the shorter the wavelength, the higher the frequency. Light with a lower frequency than 384 THz is infrared, while light with a higher frequency than 769 THz is called ultraviolet.

Answer 2

The longest visible wavelength is the one associated with the last color

you can see on the red end of the rainbow.

The shortest visible wavelength is the one associated with the last color

you can see on the blue/violet end of the rainbow.

Every different wavelength is perceived by the eye as a different color.

Answer 3

Yes, red is the longest wave length in the visible spectrum and blue is the shortest wave length in the visible spectrum. This also explains why (I won't go into scientific detail) the sky is blue during the day and turns red around sunset.

Answer 4

Wavelength is directly related to color perception. Shorter wavelengths correspond to colors seen as blue and violet, while longer wavelengths correspond to colors seen as red and orange. The visible light spectrum ranges from about 400 to 700 nanometers in wavelength.

Answer 5

well it determines the frictiong caused by an underwater earthquake, therefore a exothermic, compound mix :)

Answer 6

Red is longest wavelength, violet is shortest. The spectrum is between them.

Answer 7

that is the definition of colour or how you perceive colour.

Answer 8

The longer the wavelength, the greater the angle of refraction.

Answer 9

Yes.
