Homework Help: Velocity in vacuum

  1. Feb 9, 2006 #1
    Hi everyone anyways I have a question about finding the wavelength in a vacuum.

    I am giving that the frequency is 4.3e+14 Hz and that the wave is in a vacuum and im asked to find the wavelength. Anyways I did the calculations and I thought the velocity of a wave in vacuum is 3.0e+8 m/s is this correction, because after plugging those calculations in the webpage still says my answer is wrong.
