7.6 Exercise 23

Avg difficulty 2.5

Atoms in a crystal lattice vibrate in simple harmonic motion. Assuming a lattice atom has a mass of 9.4×10−26kg9.4 \times 10^{−26} \text{kg}, 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\text{525}- \mu \text{m} photon?
