The energy of a photon is 1.5MeV. Calculate the frequency associated with this photon energy and state an appropriate unit in your answer.

E=1.5MeV = (1.5x10^6)(1.6x10^-19)J = 2.4x10^-13J E=hf, f=E/h = (2.4x10^-13)/(6.63x10^-34)=3.6x10^20Hz

Light with a frequency of 200nm is shone on a sodium plate with a work function of 2.28eV and electrons start escaping the surface of the plate due to the photoelectric effect. What is the maximum kinetic energy of one of these electrons in eV?


Using Fermat's Principle explain why it makes sense for light be refracted when crossing from one medium into another that has a different refractive index.


How do I convert between eV and J


How would I derive Kepler's third law from Newton's law of gravitation and the equations of circular motion?
