the production of light by living organisms. Fluorescence. occurs when a material absorbs EM radiation of one wave lenght, gives off EM radiation of another. Transmission. the passage of an EM wave through a medium. Study with Quizlet and memorize flashcards containing terms like Electromagnetic wave, Radiation, Electromagnetic spectrum and more.
Which best compares the energy transferred by the two waves? 1. It is the same for each wave because the amount of energy transferred is constant in all types of electromagnetic waves. 2. Wave Y transfers about one-third the amount of energy as wave Z because energy and frequency have an inverse relationship.

Infrared Radiation. The microwave and infrared regions of the electromagnetic spectrum overlap (Figure 24.3.1). Infrared radiation is generally produced by thermal motion and the vibration and rotation of atoms and molecules. Electronic transitions in atoms and molecules can also produce infrared radiation.
