How do i find the wavenelgth of blue light?

• Physics - wavelenth of blue light -

or a radio wave or gamma ray?

• Physics - wavelenth of blue light -

Wavelength λ =c/f,
where c= 3•10^8 m/s;
reference data – frequency
f=(6.31–6.68) •10^14 Hz - blue light;
f= 3•10^16 Hz - 3•10^19 Hz – X-rays;
f = 3• 10^11 – 3•10^3 Hz - radio-waves.

thanks, but where are you getting the frequencies from?
