Activity of a radioactive sample is \(R_1\) at a time \(t_1\) and \(R_2\) at a time \(t_2\). Its half life period is \(T\). The number of atoms that have disintegrated in the time interval \(\left(t_2-t_1\right)\) is equal to \(\frac{n\left(\mathrm{R}_1-\mathrm{R}_2\right) \mathrm{T}}{\ln 4}\). Then ' \(n\) ' is equal to
- A 2
- B 1
- C 4
- D \(\frac{1}{2}\)
