I know we use wavelength x frequency= c to convert between frequency and wavelength, but what equation do we use to find the energy of the photon? I can't seem to find it in the text.

The energy of a photon is equal to Planck's constant multiplied by the frequency of light. E = hf

In more detail, multiply the given frequency by Planck's constant (h=6.626 * 10^-34).
And just if anyone wants more info on frequency to wavelength, to convert from frequency to wavelength, all you have to do is divide the speed of light (c=2.998 * 10^8 m/s) by the given frequency.

To find the energy of the photon you use the equation E=hv meaning in this case you multiply the given frequency (8.7 x 10^-14 Hz) by Planck's constant (6.626 x 10^-34).

You have to use Planck's constant, which is 6.626 x 10^-34.

Thanks for the replies! The equation needed wasn't in section 1A, but then I realized it was one of the first things to show up in 1B ^^|| I'll be sure to remember the equation from now on!
