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".
What else can I help you with?
In a light wave what properties tell you the color of the light?
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.
What properties of a light wave determine its color?
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.
Longest color wave lengths?
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.
The time it takes two successive crests of an ocean wave to pass a given point is called a?
A wave length.
How are waves measured?
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.
How does blue light differ from red light?
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.
Does red light have a longer wave length than blue light?
Red Light

Which color of light in the visible spectrum has the longest wave length?
Red light has the longest wavelength in the visible spectrum.
What happens to the wavelengths of light As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum?
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm
In a light wave what properties tell you the color of the light?

If a red light has a longer wave length than a blue light which one has a greater frequency?
the blue light
Which color invisible light has the longest wave length?
Red light has the longest wavelength in the visible light spectrum.
Which color of the rainbow has the longest wave length?
Red has the longest wavelength in the visible spectrum of light.
As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the wavelengths of the light?
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm
Do all colors have the same wave lengths?
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.
What is the color of visible light that has the longest wave length?
That's the last color you can see on the red end of the spectrum.
