- Physics 4PH1
Exam points
- Identify spectrum regions from labelled diagrams, adjacent positions or frequency comparisons.
- Link EM uses to radiation type, such as microwaves for cooking or gamma rays for sterilising.
- Explain hazards using the radiation and effect, such as UV cell damage or microwave heating.
