Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following describes the relationship between the energy of a photon and its frequency?
Directly proportional
Inversely proportional
No relationship
Exponential
2. When an electron moves from a higher energy level to a lower energy level, it:
Absorbs a photon
Emits a photon
Increases its energy
Becomes ionized
3. The energy of a photon is directly proportional to its and inversely proportional to its .
4. The Bohr model of the atom suggests that electrons occupy discrete levels.
5. Explain the concept of 'quantized energy levels' in atoms. How does this relate to the emission and absorption spectra of elements?
6. A red photon has more energy than a blue photon.
True
False
7. The photoelectric effect demonstrates the particle nature of light.
True
False
8. Calculate the energy of a photon with a frequency of 5.0 x 10^14 Hz. (Planck's constant, h = 6.626 x 10^-34 J·s)
9. Refer to the diagram of an atom's electron cloud. If an electron moves from a higher energy shell to a lower energy shell, what happens to the energy difference between these shells?
