What is the frquency of violet light with a wavelength of 408nm?

The wavelenght L = c/f so the frequency f is:

f = c/L = 3*10^8/408*10^-9 = 7.35*10^14 Hz

Hi,



By definition, frequency and wavelength are linked to the speed of light by the following formula:



c = Lf



where c is the speed of light, L the wavelength and f the frequency.



Assuming a vacuum, then the speed of light is c = 3x10^8 m/s.



Thus, all you need to do is solve for f by rearranging the equation to be:



f = c/L



In your case, you have:



f = 3x10^8 / 408x10^(-9) ~= 735 294 117 647 058 Hz



This is approximately 7.35 x 10^14 Hz or 735 THz (Tera-Hertz).



Hope this helps.
