luminous-flux density — noun : the luminous energy in a beam of light passing a unit normal section per unit time called also intensity of light … Useful english dictionary
Luminous efficacy — is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power. Depending on context, the power can be either the radiant flux of the source s output, or it can be the total electric power consumed by… … Wikipedia

Radiant energy — Visible light (a form of radiant energy) scattered by fog in a forest. Radiant energy is the energy of electromagnetic waves.[1] The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and … Wikipedia
Orders of magnitude (density) — Skylab measured several orders of magnitude of the Sun s density (top scale: 10−18 to 10−6 g⋅cm−3, equivalent to 10−15 to 10−3 kg⋅m−3) at different temperatures and heights above its surface. List of orders of magnitude for density less than … Wikipedia
Dark-energy star — A dark energy star is a hypothetical compact astrophysical object, which a minority of physicists feel might constitute an alternative explanation for observations of astronomical black hole candidates. Dark energy is invisible to the human eye;… … Wikipedia
Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… … Wikipedia
