How many electrons can be so excited

Reference no: EM13340521

A 9.0W laser beam shines on an ensemble of 1024 electrons, each in the ground state of a one-dimensional infinite square well 0.82nm wide. The photon energy is just high enough to raise an electron to its first excited state.

How many electrons can be so excited if the beam shines for 5.0ms ?
