Challenge Problems
Push your limits with challenges.
Question 1
Given the Rydberg constant \( R_H = 1.097 \times 10^7 \text{ m}^{-1} \), calculate the wavelength of light emitted when hydrogen transitions from \( n=4 \) to \( n=2 \).
💡 Hint: Break down the equation into parts.
Question 2
If you observe splitting of a hydrogen spectral line into three distinct lines under a magnetic field, what does this indicate about the Zeeman Effect?
💡 Hint: Think about the nature of the magnetic field's effect on energy levels.
