A Lithium Atom,mass 1

question 12

Essay

A lithium atom,mass 1.17 × 10^-26 kg,vibrates with simple harmonic motion in a crystal lattice,where the effective force constant of the forces on the atom is k = 49.0 N/m.
(c = 3.00 × 10⁸ m/s,h = 6.626 × 10^-34 J ∙ s,h = 1.055 × 10^-34 J ∙ s,1 eV = 1.60 × 10^-19 J)
(a)What is the ground state energy of this system,in eV?
(b)What is the wavelength of the photon that could excite this system from the ground state to the first excited state?
