A quantum harmonic oscillator makes a transition from the state to the state and emits a photon that has a wavelength of 0.450 μm. What is the oscillator’s frequency?
Atoms in a crystal lattice vibrate in simple harmonic motion. What is the force constant of the lattice if a lattice atom makes a transition from the ground state to first excited state when it absorbs a 525-μm photon? Use a value of kg for the mass a lattice atom.
