Challenge Problems
Push your limits with challenges.
Question 1
Given that the wavelength of light emitted when an electron transitions from n=4 to n=2 in hydrogen is known, derive the energy change this transition represents.
💡 Hint: Remember to convert the wavelength into meters.
Question 2
Discuss why the Bohr model's predictions for helium differ from observed spectra. Provide a theoretical explanation.
💡 Hint: Consider the implications of additional electrons.
