Question

You buy a 5 milli-watt green laser with wavelength 532 nm. (1 nanometer is 10-9 meters). What is the energy in

Joules of an individual photon in the beam? (I remind you that Planck’s constant is h = 6.63 x 10-34 Js and the speed of light is c = 3 x 108 m/s). You can write the exponents in your answer using the symbol ^ like this h=6.63 x 10^-34.
