Q2. A collection of N atoms is exposed to a strong resonant electromagnetic radiation with Ng atoms in the ground state and Ne atoms in the excited state, such that Ng+N=N. This collection of two-level atoms will have the following population distribution: (a) N<< N. (b) Ng>> N. (c) NN, N/2 (d) N-N,* NI2
