Answer:

Electromagnetic waves and atomic structure

Quantum concepts

Quantum mechanics includes such concepts as “allowed states”—i.e., stationary states of energy content exactly stipulated by its laws. The energy states shown in Figure 1 are of that kind. A transition between such states depends not only on the availability (e.g., as radiation) of the precise amount of energy required but also on the quantum-mechanical probability of such a transition. That probability, the oscillator strength, involves so-called selection rules that, in general terms, state the degree to which a transition between two states (which are described in quantum-mechanical terms) is allowed. As an illustration of allowed transition in Figure 1, the only electronic transitions permitted are those in which the change in vibrational quantum number accompanying a change in electronic excitation is plus or minus one or zero, except that a 0 ↔ 0 (zero-to-zero) change is not permitted. All electronic states include vibrational and rotational levels, so that the probability of a specific electronic transition includes the probabilities of transition between all the vibrational and rotational states that can conceivably be involved. Figure 1 is, of course, a simplified picture of a compendium of energy states available to a molecule (polyatomic structure)—and the selection rules are accordingly more involved in such a case. The selection rules are worked out by scientists in a process of discovery; the attempt is to state them systematically so that the applicable rules in an experimentally unstudied case may be stated on the basis of general principle.

Explanation:

The study of EM is essential to understanding the properties of light, its propagation through tissue, scattering and absorption effects, and changes in the state of polarization. ... Since light travels much faster than sound, detection of the reflected EM radiation is performed with interferometry.
