A chick hatching from an egg. The chicken or the egg causality dilemma is commonly stated as which came first: the chicken or the egg?. The dilemma stems from the observation that all chickens hatch from eggs and all chicken eggs are laid by chickens.
Unpolarized light can also become polarized when it is scattered in air (also known as Rayleigh scattering). This occurs due to the fact that the EM waves cause the electron in air to vibrate, producing radiation and causing polarization of the light.
Radiation occurs whenever something spreads out along the radii of the system. [You see where the word comes from.] Sound radiates, as does heat and light. Atomic radiation, â¦ or radioactivity also radiates out in all directions. Unless otherwise constrained. It occurs when a disintegration occurs within the nucleus of an atom. Radiation also occurs with populations of plants and animals. When introduced into a new environment, a species is said to radiate as it spreads out.
