Homework Help: Frequency of light

  1. May 5, 2008 #1
    1. The problem statement, all variables and given/known data

    The speed of light is 3 x [tex]10^8[/tex] m/s. Blue light has a wavelength of about 450nm (nm = 10^-9 m). Calculate the frequency of this light

    2. Relevant equations

    v=f[tex]\lambda[/tex]

    3. The attempt at a solution

    3 x [tex]10^8[/tex] = f x 450
    f = [tex]\frac{3 times 10^8}{450}[/tex]
