Answer:

1. Given that the wavelength of the photon required to promote an electron in the hydrogen atom from the n = 1 to the n = 3 level is lt the wavelength of the photon required to promote an electron in the hydrogen atom from the n = 1 to the n = 2 level.

2. Given that the energy of a photon with a wavelength of 463 nm is gt the energy of a photon whose wavelength is 722 nm.

3. Therefore, in order to promote an electron to go to a higher energy level, light with a wavelength that is lt 400 nm is required

Explanation:

The equation for electron transition in a hydrogen atom is given by the Rydberg equation as follows;

[tex]\dfrac{1}{\lambda} = R \times \left (\dfrac{1}{n^2_f} - \dfrac{1}{n^2_i} \right )[/tex]

The energy required for electron transition is given by the formula;

[tex]E = \dfrac{h \cdot c}{\lambda}[/tex]

[tex]E = R_E \times \left (\dfrac{1}{n^2_f} - \dfrac{1}{n^2_i} \right )[/tex]

Where;

h = The Planck's constant

λ = The wavelength of light

c = The speed of light

n = Specific energy level

[tex]R_E[/tex] = -2.178 × 10⁻¹⁸ J

Therefore, the energy required to move an electron from one energy level to a higher energy level is inversely proportional to the wavelength of light, λ.

Increase in λ, results in lower energy available to transition to a higher energy level while a decrease in λ results in more energy available to transition to a higher energy level.
