Need help calculating frequency

    Read my Journal nd hlp. calculating frequency


    I have a problem that states as follows:

    Calculate the frequency (in Hz) of energy of 3.5 x 10^-14 joules. (c=3.00 x 10^8 m/s; h=6.63 x 10^-34 joule-seconds)

    I need help in setting this problem up. I found the equation E=hv, where E= the increase of energy, h= planck's constant, and v= the freqency of light which increases propportionally with an increase in energy.

    I am going crazy and just don't get it...........

    [tex] E = h\nu \Rightarrow \nu = \frac{E}{h} [/tex]

    [tex] E = 3.5 \times 10^{-14} J, h = 6.63 \times 10^{-34} J\cdot s[/tex]

    Welcome to Physics Forums, middleearth77!

    This sounds like a homework problem, so I'm moving it to the appropriate section.
