Calculating the total energy of photons from a helium-neon laser.

A helium-neon laser gives off redlight with a wavelength of 632.8 nm (nanometers). What is the energy of the photons coming out of the laser?

(Hint: the speed of light is 3x10 [to the 8th pwr.] m/sec.)

SIDE NOTES:
We have been using very basic equations in this class, it is not advanced or anything. I do not know which equation(s) to use first of all or how to work it out. I need to show ALL work including formulas and steps, possibly drawings to. Thanks in advance!
