The color of the wavelength lambda = 685 nanometers is "deep red". The wavelength lambda = 685 nanometers equals the frequency f = 503,852,870,588,235 Hz. 1 nanometer = 1×10−9 meter. 685 nm = 0.000000685 meters. Scroll down to related links and look at "Radio and light waves in a vacuum".
Visible light has wavelengths between about 400 and 700 nm; the longer wavelengths correspond to red light, so about 700 nm.
Red light has wavelengths in the range 620–750 nm.
~625-740 nm
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.
Frequency or wave length.The relation between frequency f and wave length lof a light waveis given by; f = c/l, where c is light's speed.
There is no longest wave-length for light. It can be infinitely long (just as light waves could be infinitely short). The longest visible light that humans can see is about 750 nanometers long, which is 0.00075 of a millimeter. This color would be a shade of red. Some other animals and insects can see slightly longer wavelengths, and many can not even see what we can.
It depends, if you mean light or sound waves, for example, there are a variety of factors to be measured: The length of a wave from peak to peak is represented with lambda. You can also measure velocity of a wave (how fast and in what direction it is moving). Frequency of light effects the color of the light, and frequency of sound effects its pitch.
A wave length.
red and blue light differ in wave length because blue lights have shorter wave length than red light and shorter wave length are good for plants germination.

It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm

Visible light wavelengths fill the electromagnetic spectrum between red wavelengths and violet wavelengths.
The violet colour will be refracted the most, it has a shorter wave length and a higher frequency. The red light will be refracted the least, with its longer wave length and lower frequency.
The visible light part of the electromagnetic spectrum is below the ultraviolet but above infrared. Purple light has the highest wave length and red has the lowest.
