Can someone please help me with this this probablem involves 2 circles. One containing E (energy) on the top and h and v on the bottom. Now, the other is C (speed of light which is 3.00 X 10 to the 8th power and wavelenght and frequency on the bottom. Please please help, I have a test on this stuff tomorrow...I get the concept...but really need help...I know how to do it when it involves one circle but not when it involves tow circles. :(

You seem to be overthinking this. If you know the equation E=hv [energy=Planck's constant(frequency)], you can easily solve for frequency without finding any other variables; v=E/h [frequency=energy/Planck's constant]. E=4.56(10^-9) and h=6.67(10^-34), so v=4.56(10^-9)/6.67(10^-34).

The frequency nu, a Greek letter which looks a bit like a v, is 4.56x 10^-9 divided by Planck's constant, which is 6.67 x 10^-34 joule seconds. I make that 6.8x10^24 Hz. This is a gamma ray frequency.

In words, energy = frequency x Planck's constant
The symbol used for frequency is a Greek nu, whichlooks a bit like a v squashed sideways.
