f=c/lambda frequency = 299792458 divided by wavelength The freq is in Kilohertz, and the wavelength is in meters. A nanometer is one billionth of a meter. I'll let you figure out how to move the decimals points.

∙ 14y agoAll electromagnetic waves travel at the speed of light, which is 299,792,458 meters per second. In any electromagnetic radiation, the frequency times the wavelength is the speed of light.
You can calculate the frequency of the light by dividing the speed of light by the wavelength. You can use Google as a calculator and units converter by typing the formula into the search window.

What is the frequency of a blue light with a wave length of 469 nanometers?
Frequency is in cycles per unit time Wavelength is in length per cycle To convert between the two you need the speed of the wave - which for light is the speed of light - which is given in length per unit time Frequency = Speed of light/Wavelength For a wavelength of 469 nanometers Frequency is 639 Terahertz (THz) or 639,000 Gigahertz (GHz) ... rounded to 3 significant digits since the wavelength is only given to 3 significant digits
What color is the light spectrum with a wavelength of 450 to 420 nanometers?
Blue light
Does yellow light have more energy than green light?
Yes. Blue light has a lower wavelength than yellow light, which is why it is perceived by out eyes as a different color. Blue light's wavelength is around 450 nanometers and yellow light's wavelength is around 575 nanometers. since the speed of light is constant for all light, and frequency is the speed of light over the wavelength of the light, the larger the wavelength, the lower the frequency. And the lower the frequency, the lower the energy. So the shorter wavelength of light (in this case, blue colored light) has a faster frequency, and therefore more energy.
Between green light and red light which has a higher frequency?
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack
What is the frequency of blue light that has a wavelength of 451 nm?

If blue light has a frequency of 6.98 10 14 hertz what is the wavelength in nanometers?
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
Which color of visible light has the highest frequency?
blueee!!

How do the wavelength and frequency of red light compare to the wavelength and frequency of blue light?
very nice answer.
If a ray of light has a wavelength of 465 nanometers, what shade of visible light does it produce?
Blue
What is the frequency of red light that has a wavelength of 645 nm?
The color of the wavelength lambda = 595 nanometers is "orange-yellow" and not blue. The wavelength lambda = 595 nanometers equals the frequency f = 503,852,870,588,235 Hz. Blue light is between 490 and 450 nonometers. 1 nanometer = 1×10−9 meter. 595 nm = 0.000000595 meters. Scroll down to related links and look at "Radio and light waves in a vacuum".
