A ruby laser is a red laser with a wavelength between 694 nm and 628 nm. 1 nanometer = 1×10−9 meter.
it is short wavelength
Just ONE property, the wavelength of the light. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end.
For visible light, the wavelength will usually be specified in nm (nanometers).
If you are talking specifically about visible light, the wavelength is between approximately 380 nm and 760 nm, depending on the color.

A ruby laser is a red laser with a wavelength between 694 nm and 628 nm. 1 nanometer = 1×10−9 meter.
Visible light ranges from red at about 750 nm to violet at around 400 nm.
Light's color depends on its wavelength. Shorter wavelengths make light more red, while longer make it more violet colored. Red light has a wavelength of approximately 700 nm, while violet light has a wavelength of 400 nm.
Waves of bright green light have higher frequency (shorter wavelength) and higher amplitude than waves of dim red light have. For example, if the colors were red and blue, Red light has a wavelength of 750 nm and blue light has a wavelength of 500 nm. Their wavelengths will differ.
it is short wavelength
If a wavelength of light emitted from a particular red diode laser is 651 nm, its wavelength would be equivalent to 0.000000651 meters.
670.8 nm is the wavelength.
Violet: 380 - 450 nm Blue: 450 - 475 nm Green: 495 - 570 nm Yellow: 570 - 590 nm Orange: 590 - 620 nm Red: 620 - 750 nm 'nm' means 'nanometre'. One nanometre is 0.000000001 metres.
