BPH2101 PHYSICS REMAINING TIME HOURS MINUTES SECONDS 1 46 5 46 Why is laser light monochromatic O Photons of the same energy as that of the incident photons are emitted when the electrons transit down from a higher energy level The system is in a state of population inversion A O The emitted photon and incident photon are of the sam phase The excited electrons are in a metastable state
