What is the equation to find wavelength of red light with a frequency of 4 x 10^14

Sagot :

AL2006

If you know the frequency, then the equation to find the wavelength
of ANY wave is

           Wavelength = (wave speed) / (frequency) .

Since we're talking about light, we'll use  3 x 10^8 m/s for a speed.

           Wavelength = (3 x 10^8 m/s) / (4 x 10^14 /sec) =

                                               7.5 x 10^-7 meters  =

                                                750 nanometers
