If you are talking specifically about visible light, the wavelength is between approximately 380 nm and 760 nm, depending on the color.
The wavelength for the color red is 700-635 nm, which can also be said as 700 to 635 nanometers.
Purple is a mixture of the colors red and blue.
Approximately in the range of 350-700 nm, depending on the color.
about 435 nm
The color is red.
If you are talking specifically about visible light, the wavelength is between approximately 380 nm and 760 nm, depending on the color.
Originally, CD lasers with a wavelength of 780 nm were used, in the infrared.For DVDs, the wavelength was reduced to 650 nm (red color), and the wavelengthfor Blu-ray Disc was reduced to 405 nm (violet color).
Blue
This is the violet color (380-450 nm).
Blue is part of the colour spectrum, with a wavelength of about 475 nm.
The wavelength for the color red is 700-635 nm, which can also be said as 700 to 635 nanometers.
The wavelength of the color violet is 450-400 nm, which can also be said as 450 to 400 nanometers.
The standard wavelength for the color green is 560-490 nm, which can also be said as 560 to 490 nanometers.
Purple is a mixture of the colors red and blue.
670.8 nm is the wavelength.
Approximately in the range of 350-700 nm, depending on the color.
