200nm, 300 nm, and 500nm.
a) Draw the atom's energy level diagram. Label each level with
the energy and the principal quantum number.
b) What wavelengths are seen in the atom's emission
spectrum?

One series of lines in the hydrogen spectrum is caused by
emission of energy accompanying the fall of an electron from outer
shells to the fourth shell. The lines can be calculated using the
Balmer-Rydberg equation:
1λ=R∞[1m2−1n2]
where m=4, R∞ = 1.097×10−2nm−1, and nis an
integer greater than 4.
Part A
Calculate the wavelengths in nanometers of the first two lines
in the series.
Express your answers using four significant figures separated by
a comma.
Part B
