Understanding This Calculator
Nuclear Physics Formulas
Equations for decay and energy.
- Decay: N(t) = N₀ × e^(-λt)
- Half-Life: T½ = ln(2) / λ ≈ 0.693 / λ
- Energy: E = mc²
Example 1 (Half Life)
λ = 0.1 s⁻¹
- T½ = 0.693 / 0.1 = 6.93 s
Example 2 (Energy)
Mass Defect: 1u (1.66e-27 kg)
- E = 1.66e-27 × (3e8)² ≈ 1.49e-10 J
How to Use
- Enter initial amount and decay constant for radioactive decay.
