Hydrogen atoms absorb energy so that the electrons are excited to n=4. Calculate the wavelength, in

FromTheMoon [43]

Answer:

the wavelength, in nm, of the photon is 487.5 nm

Explanation:

Given:

n = 4 (excited)

n = 2 (relaxes)

Question: Calculate the wavelength, in nm, λ = ?

First, it is important to calculate the energy of the electron when it excited and then when it relaxes.
