📖 Theory – ☢️ 11. Nuclear Physics
The nucleus contains protons and neutrons.
Radioactive decay: alpha (α), beta (β), gamma (γ) decay.
The decay law: N = N₀e^(-λt).
Half-life t₁/₂ = ln2/λ.
Fission: splitting a heavy nucleus into smaller nuclei.
Fusion: combining light nuclei into a heavier nucleus.
Nuclear reactors use controlled fission.
Mass-energy equivalence: E = mc².
