Calculating the total energy of photons from a helium-neon laser.
A helium-neon laser gives off red light 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.)
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!
... uses a constant, called Planck's constant, which is called h and equals 6.6x10^(-34)Joules*seconds.
