All Modern Physics Concepts
Radioactive Decay
Radioactive decay is the spontaneous change of an unstable atomic nucleus into a more stable one, often releasing particles or electromagnetic radiation in the process.
Nuclear Fission
Nuclear fission is the splitting of a heavy nucleus into smaller nuclei, releasing energy and often additional neutrons.
Nuclear Fusion
Nuclear fusion is the joining of light nuclei to form a heavier nucleus, releasing energy if the final nucleus is more tightly bound.
Photoelectric Effect
The photoelectric effect is the emission of electrons from a material when light of high enough frequency shines on it.
Special Relativity
Special relativity is Einstein's theory describing physics at very high speeds, where measurements of time, length, and simultaneity depend on the observer's frame of reference.
