Interaction of Light and Matter 8.1 Electromagnetic Waves at an Interface A beam of light (implicitly a plane wave) in vacuum or in an isotropic medium propa-gates in the particular ﬁxed direction speciﬁed by its Poynting vector until it encoun-ters the interface with a diﬀerent medium. The light causes the charges (electrons,

Attosecond science refers to physical processes that occur on the natural timescale of electron Interaction of Light and Matter Atomic or molecular gases in low concentration show sharp energy eigen spectra. This was shown for the hydrogen atom. Usually, there are inﬁnitely many energy eigenstates in an atomic, molecular or solid-state medium and the spectral lines are associated with allowed transitions between two of these 2008-02-07 Classically, light-matter interactions are a result of an oscillating electromagnetic field resonantly interacting with charged particles. Quantum mechanically, light fields will act to couple quantum states of the matter, as we have discussed earlier.
