jee-mainjee-advancedneet-ug
N = N₀ e^(−λt)
What each symbol means
| Symbol | What it stands for |
|---|---|
| t | Time (s) |
| λ | Decay constant (s⁻¹) |
| N_0 | Initial count at t=0 |
| N(t) | Number of undecayed nuclei at time t |
When to use this
Independent decay; statistical limit large N; secular equilibrium not assumed.
