Consider the spacing of vibrational energy levels of materials X and Al based on the quantum harmonic oscillator model for interatomic bonds. X is a hypothetical material of stiffness ks = 2N/m and atomic mass 200 mN (where mN is the mass of a nucleon). The interatomic stiffness of Al is ks = 17N/m, and its atomic mass is 27 mN. What is the ratio of the energy level spacings, ∆EX ∆EAl ?

The ratio is

Explanation:

From the question we are told that

         The stiffness is

          The  atomic mass is

          The inter-atomic stiffness of Al is

          The atomic mass of  AI is

The ratio of the energy is mathematically represented as

graph question answered .. you think better when you are relaxed and happy

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
