Exam-style question
Try this first
How can you determine the energy of a photon emitted during an electron transition?.
- A.By measuring the wavelength of the photon
- B.By calculating the difference between energy levels
- C.By using the mass of the electron
- D.By observing the color of the emitted light
Model answer
What a good answer should say
- By calculating the difference between energy levels
Explanation
Why this works
The energy of the emitted photon can be calculated using the difference in energy between the two atomic energy levels involved in the transition.
