radiant energy is the
energy of
electromagnetic and
gravitational radiation. As
energy, its SI unit is the
joule (J). The

- In radiometry,
radiant flux or
radiant power is the
radiant energy emitted, reflected, transmitted, or
received per unit time, and
spectral flux or spectral...
- radiometry,
radiant energy density is the
radiant energy per unit volume. The SI unit of
radiant energy density is the
joule per
cubic metre (J/m3).

Alternative symbols sometimes seen: W or E for
radiant energy, P or F for
radiant flux, I for irradiance, W for
radiant exitance.

- In radiometry,
radiant exitance or
radiant emittance is the
radiant flux
emitted by a
surface per unit area,
