  • The greenhouse gases quickly reemit, or release, the absorbed heat energy, with approximately 50 percent of the reemitted energy directed back toward the Earth's surface.

    Academic text (1992)
  • But atoms in a material (e.g., a crystal or an amorphous material like glass) can absorb and reemit across a broad spectrum because you also have the phonon (vibrational) modes.

Morphology

reemit = emit (transparent) = re + emit

This is standard prefixation of 're-' onto 'emit', giving the clear meaning 'emit again'.

Etymology

Reemit comes from the prefix re- 'again' and the word emit 'send out'. Think of a material that soaks up sunlight like a sponge and then 'squeezes' the energy out again as heat, so to reemit is to send out energy again.
