2. "Regular" particles "accommodate" the energy they carry in their mass and velocity, and their frequency (or wavelength) is tied to those properties (e.g. de Broglie wavelength). The energy of a photon, on the other hand, appears to be arbitrary, i.e. not tied to mass (which is zero) nor speed (which is the speed of light).

Hydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water. Hydropower relies on the endless, constantly recharging system of the water cycle to produce electricity, using a fuel—water—that is not reduced or eliminated in the process.

The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let''s examine each of these characteristics.

FIG. 1. Types of single-photon sources: (a) isolated quantum systems (e.g. a single particle in an optical cavity, with ground g and excited e states), (b) heralded single-photon sources from photon pairs, (c) multiplexed source (as one example, spatial multiplexing is shown). Each of these approaches has advantages and drawbacks.
When a parent molecule is exposed to light, the incoming photon should be able to excite the molecule from the ground state (S 0) to an excited state (S excited) via a photon absorption process (A).Afterward, the excited molecule undergoes a photoconversion process into the metastable high-energy photoisomer, with a certain …
