Short Answer

I FIGURE EX38.24 is an energy-level diagram for a simple atom. What wavelengths, in \mathrm{nm}, appear in the atom's (a) emission spectrum and (b) absorption spectrum?

FIGURE EX38.24 n=1-E_{1}=0.00 \mathrm{eV}

a)

b)

See the step by step solution

Step by Step Solution

part (a) step 1 : given information

We can start the solution with expression for wavelength from transition

part (b) step 1 : given information

Atom is in the n=1 state, so we have only absorption from and . Expressions are same, so wavelengths are same.
