Step 1

It is given that:

Wavelength = 618 nm

Electron is exciting from n = 2 to n = 4 level

Step 2

The energy of an electron in one dimension is represented as follows: help_outlineImage Transcriptionclosen2h2 8mL where, n is the energy level h is planck's constant(h =6.626x1034 kgm's1 m is mass of an electron (m = 9.109x 1031 kg L is length of the box fullscreen
Step 3

Also, energy can be expressed in terms of Planck’s constant(...
