Question:

Consider a particle in a box of length {eq}1.0 \, \mathrm{nm} {/eq}. What is the photon energy required to excite an electron from the ground state to the second excited state?

Excited state of Electron:

When an electron jumps from a higher energy state to a lower energy state it emits energy in the form of light.

The energy required to excite an electron from lower to higher energy state is given as -

{eq}\displaystyle \triangle E = \frac{h^2}{8m_ed^2}(n_2^2 - n_1^2)\\ {/eq}

Answer and Explanation:

Photon energy required to excite an electron from ground to second excited state is given as -

{eq}\displaystyle \triangle E = E_2 -...
