Unit 4 Physics Area of Study 1 Practice: Modern Physics

Criterion-by-criterion practice for VCE Physics Unit 4 AOS 1, with 163 exam-style questions across 36 skill criteria and 8 topics: single slit diffraction, Young's double slit experiment, the photoelectric effect, standing waves on a string fixed at both ends, matter as a wave, photon momentum, atomic absorption and emission spectra, and special relativity. Pick a criterion from the sidebar and work through its questions: 131 short-answer items with mark allocations and 32 multiple choice. Numerical answers can be typed into a maths input and checked automatically against a tolerance, and every question reveals a worked solution broken into separate steps showing where each mark is earned. Self-marking with Got it / Partly / Missed fills a per-criterion progress bar so gaps are visible at a glance, and progress is saved in the browser between sessions. All diagrams are embedded in the page itself.
