Observation

Performance was fair however, some candidates confused dual nature (wave-particle) of light with the general characteristics of waves.

The expected answer is:

Phenomena that illustrates particle nature of light

- Photoelectric effect
- Radiation of energy from heated bodies
- (general) emission/absorption of light
- Compton effect.
