What is the frequency of radiation with a wavelength of 5.00 x 10^-8m

The frequency of radiation with a wavelength of 5.00 x 10^-8m is  

6 x10¹⁶s⁻¹

In Physics, For Electromagnectic waves/radiation, there exist a  relationship between the frequency  and wavelength in that they are inversely proportional to each other which we can see by the  formula,

λ  = c / f

where

c is the speed of light, 3 x 10 ⁸m/s

λ the wavelength in meters,m and

f is  the frequency in cycles per second.

λ  = c / f

f = c /  λ

f    = ( 3 x 10 ⁸m/s) / (5.00 x 10⁻⁸m)

f  =  6 x 10¹⁶s⁻¹
