For a particle is in a box with a ground state energy of 4 eV, energy absorbed is mathematically given as
dE=20eV
What energy must be absorbed by the system to go from the n?
Generally, the equation for the energy absorbed is mathematically given as
En=n^2E1
Therefore
dE=E3-E2
dE=3^2-2^2)E1
dE=20eV
In conclusion, the energy is
dE=20eV
