Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body. Ferranti effect — A rise in the amplitude of the AC voltage at the receiving end of a transmission line, compared with the sending-end voltage, due to the capacitance between the conductors, when the receiving end is open ...
The heating effect varies with the power and the frequency of the electromagnetic energy, as well as the inverse square of distance to the source. The eyes and testes are particularly susceptible to radio frequency heating due to the paucity of blood flow in these areas that could otherwise dissipate the heat buildup.
Quantum effects provide additional sources of EMR, such as the transition of electrons to lower energy levels in an atom and black-body radiation. [9] The energy of an individual photon is quantized and proportional to frequency according to Planck's equation E = hf, where E is the energy per photon, f is the frequency of the photon, and h is ...
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
Ferroelectric effect (condensed matter physics) (electrical phenomena) Fink effect (anesthesia) (diffusion) Flaming sword (effect) (fire arts) (special effects) Floating body effect (electronics) (semiconductors) Floodgate effect (social phenomena) (sociology) Floor effect (statistics) Florence Nightingale effect (Florence Nightingale) (love ...
A mysterious light has been blinking in space every 21 minutes for 35 years–and scientists have no idea what it is. What could it be?
The effect is blunted by Earth's surrounding atmosphere, and particularly the water vapor it contains, so the apparent temperature of the sky is far warmer than outer space. The sheet does not block the cold, but instead reflects heat to the face and radiates the heat of the face that it just absorbed.
