Document Summary
Most energy animals communicate with is from the sun. Some of the animals use energy they produced themselves. Light is a form of electromagnetic energy , with oscillating electric field and oscillating magnetic field at right angles to each other. An electromagnetic wave, produced by an oscillating electron. Electric field generating magnetic field, and the magnetic field generating magnetic field, etc. Em radiation is generated when the motion of electrons in atoms and molecules is accelerated due to input energy. The vibrating negatively charged electron generates an electric field which induces a magnetic field. Coupled electric and magnetic oscillations move outward at the speed at which they mutually induce each other indefinitely = c. When electrons are accelerated by close approach to ions. Some of the kinetic energy of the electron is absorbed by the ion, the electron has to enter a higher orbital state.
