Question

# Calculate the frequency of the light emitted when an electron in a hydrogen atom makes each transition. a. $n=4 \longrightarrow n=3$ b. $n=5 \longrightarrow n=1$ c. $n=5 \longrightarrow n=4$ d. $n=6 \longrightarrow n=5$

Determine the frequency $v$ of emitted light if an electron from the hydrogen atom makes the transition in energy levels.

a. $n = 4 \rightarrow n = 3$

b. $n = 5 \rightarrow n = 1$

c. $n = 5\rightarrow n = 4$

d. $n = 6\rightarrow n = 5$

Solution: Use $\Delta E_\text{atom} = \Delta E_\text{f} - \Delta E_\text{i}$ and $E = hv$.
