1) Calculate the energy in eV of an IR photon with a frequency of 2.90x10^13 Hz.
2) How many of these photons would need to be absorbed simultaneously by a tightly bound molecule to break it apart?
3) What is the energy in eV of a gamma ray with a frequency of 2.90x10^20 Hz?
4) How many tightly bound molecules could a single gamma ray break apart?
