Calculate the wavelength for red light

  1. Oct 2, 2009 #1
    1. The problem statement, all variables and given/known data

    The frequency of red light is 430THz calculate its wave length. Is the answer below correct?


    2. Relevant equations

    (3*10^8) / (430*10^12) = wave length


    3. The attempt at a solution

    (3*10^8) / (430*10^12) = 6.98 to 1 Decimal Place
