Modern Physics — Chapter overview · Physics & Environmental Science, Grade 12
Compare wave–particle evidence, relativistic limits, and nuclear mass-energy accounting.
Chapter question
Which observations require models beyond everyday mechanics?
Units in this chapter
- Unit 7.1 · Photons, Photoelectric Effect & Wave–Particle Models
I can explain threshold and intensity evidence for photoelectric emission.
- Unit 7.2 · Relativity, Light Speed & Model Limits
I can define inertial frames, proper time, and proper length.
- Unit 7.3 · Mass–Energy, Nuclear Reactions & Radiation Evidence
I can relate a consistent rest-mass difference to released energy.
