Energy of a Photon
Calculate the energy of one photon of yellow light that has a wavelength of 589 nm.
(a) A laser emits light that has a frequency of 4.69 × 1014 s-1. What is the energy of one photon of this radiation?
(b) If the laser emits a pulse containing 5.0 × 1017 photons of this radiation, what is the total energy of that pulse? (c) If the laser emits 1.3 × 10-2 J of energy during a pulse, how many photons are emitted?
