Question 1.
What does the Rydberg constant (R_H) represent?
Show hintHide hint
Think about what constants do in equations.
Question 2.
Describe what happens when an electron transitions from a higher to a lower energy level.
Show hintHide hint
Consider what energy must be conserved.
3Question 3.
What is R_H in the context of the Rydberg formula?
- The electron charge
- A constant related to energy levels
- The speed of light
Show hintHide hint
Consider the constants used in quantum mechanics.
4Question 4.
True or False: The wavelength of emitted light depends on the energy difference between two energy levels in an atom.
- True
- False
Show hintHide hint
Think about how energy connects to light.
Question 5.
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.
Show hintHide hint
Follow the process of substituting values step-by-step into the Rydberg formula.
Question 6.
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.
Show hintHide hint
Consider the spacing of energy levels are tighter near the nucleus compared to those farther out.
