Teaching MPPSC Assistant Professor Mock Test Series 2025 Chemical Sciences Basic Principles of Quantum Mechanics Particle-in-a-box
The correct statement about the difference of second and first excited state energies (ΔE) of a particle in 1-D, 2-D square and 3-D cubic boxes with same length for each, is
1
ΔE (1 – D box) = ΔE (2 – D box) = ΔE (3 – D box)
2
ΔE (1 – D box) > ΔE (2 – D box) > ΔE (3 – D box)
3
ΔE (1 – D box) > ΔE (2 – D box) = ΔE (3 – D box)
4
ΔE (1 – D box) < ΔE (2 – D box) < ΔE (3 – D box)
