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.

  • Physics - wavelenth of blue light -

    thanks, but where are you getting the frequencies from?
