internal photoelectric effect
oskar-e šid-barqi-ye daruni
Fr.: effet photoélectrique interne
The → photoelectric effect whereby photons absorbed by a solid (→ semiconductor) raise electrons from a lower to a higher → energy level (from → valence band to → conduction band). See also → external photoelectric effect.
internal structure of stars
sâxtâr-e daruni-ye setâregân (#)
Fr.: structure interne des étoiles
The physical characteristics of that part of a star lying below the → photosphere. More specifically, the study of its various zones (→ core, → convective zone, → radiative zone) and the transfer of energy through them.
kâr-e daruni (#)
Fr.: travail interne

In these conditions the light will not pass through to the second → medium at all. Instead, all of it will be reflected back into the first medium.
