Question 1

What is R_H in the context of the Rydberg formula?

  • The electron charge
  • A constant related to energy levels
  • The speed of light

💡 Hint: Consider the constants used in quantum mechanics.

Question 2

True or False: The wavelength of emitted light depends on the energy difference between two energy levels in an atom.

  • True
  • False

💡 Hint: Think about how energy connects to light.

Challenge Problems

Push your limits with challenges.

Question 1

A hydrogen atom's electron transitions from n=5 to n=3. Calculate the wavelength of the emitted photon. Use R_H = 1.0968 × 10⁷ m⁻¹.

💡 Hint: Follow the process of substituting values step-by-step into the Rydberg formula.

Question 2

If an electron transitions from n=3 to n=1 instead, discuss qualitatively how the emitted photon compares in energy to that of n=4 to n=2.

💡 Hint: Consider the spacing of energy levels are tighter near the nucleus compared to those farther out.
