Question

Q3. a) As the size of the box increases, what happens to the energy difference between states of a particle in the box? Will excitation from the n=1 to the n=2 state require a longer or shorter wavelength as the box increases in size? Use equations to explain your answers.

Answer 1

Here the wavelength is proportional to the square of the length of the box. If we increase the length of the box then the wavelength will also increase
