Answer:
7.11 x 
Hz
Explanation:
The equation for converting wavelength to frequency is ν=c/λ, or the speed of light over wavelength. The speed of light is 3.00 x 
, and our wavelength here is 422 x 
. All we have to do now is substitute our given values:
After reduction, our answer comes out to be about 7.11 x Hz.
