Quizplus · Accepted Answer

Laser light is coherent, meaning that it has a fixed phase relationship between the electric and magnetic fields. It is also produced by an inverted population of atoms, where more atoms are in higher energy levels than in lower levels, resulting in stimulated emission of radiation. Laser light does not contain a full spectrum of wavelengths, as it is composed of only one specific wavelength.
