Determine the end (final) value of n in a hydrogen atom transition, if the electron starts in and the atom emits a photon of lig
Usimov [2.4K]

Complete Question

Determine the end (final) value of n in a hydrogen atom transition, if the electron starts in n=4 and the atom emits a photon of light with a wavelength of 486 nm. Group of answer choices

Answer:

n=2

Explanation:

From the question we are told that:

Wavelength \lambda=486nm=>486*10^{-9}

Generally the equation for Atom Transition is mathematically given by

\frac{1}{\lambda}=R_{\infty }(\frac{1}{n_1^2}-\frac{1}{n_2^2})

Where

Rydberg constant R_{\infty}=1.097*10^7

Therefore

\frac{1}{486*10^{-9}}=1.097*10^7*(\frac{1}{n_1^2}-\frac{1}{4^2})

(\frac{1}{n_1^2}-\frac{1}{4^2})=\frac{1}{486*10^{-9}*1.097*10^7}

n_1^2=3.98

n=1.99

n=2
