The diagram shows the energy level transitions in a hydrogen
atom that result in the emission of a visible photon.
An illustration of energy levels shows the colors of the lines
of the Balmer series. The bottom energy level in the diagram
is n = 2, and an upward arrow indicates that
energy increases with higher energy levels, labeled up
to n = ∞, where E = 0.00 eV. The energy
of n = 2 is −3.401
eV, n = 3 is −1.512
eV, n = 4 is −0.8504 eV,
and n = 5 is −0.5442 eV. Balmer lines are
produced when an electron jumps to n =
2 from any higher level. Red color is emitted during
transition from n = 3, green color during
transition from n = 4, blue color during
transition from n = 5, and violet color
during transition from n = 6.
Consider the photon that appears blue in the figure.
(a) Determine its energy.
________ eV
