3. The vibration of an HBr molecule can be approximated as a harmonic oscillator with a mass equal to the reduced mass of an HBr molecule and a force constant of 354 N m*'. What is the difference in energy between the v=1 and the v=2 vibrational energy levels for this harmonic oscillator?

The image represents the gaps between allowed energy levels for electrons. Which model best describes this phenomenon? A. the wave model because electrons orbit the atom's nucleus in a continuous way B. the particle model because electrons are particles C. the wave model because the arrows show that the energy transfer is continuous D. the particle model because the arrows represent discrete particle-like jumps
