question 163

Multiple Choice

The figure shows part of the energy level diagram of a certain atom. The energy spacing between levels 1 and 2 is twice that between 2 and 3 . If an electron makes a transition from level 3 to level 2 , the radiation of wavelength $\lambda$ is emitted. What possible radiation wavelengths might be produced by other transitions between the three energy levels?

• A) only \(\lambda / 2\)
• B) both \(\lambda / 2\) and \(\lambda / 3\)
• C) only \(2 \lambda\)
• D) both \(2 \lambda\) and \(3 \lambda\)
