Exposure to the very high intensity electromagnetic fields found in the immediate vicinity of certain sources such as radar installations and TV or radio transmitters can produce electrical shock or a variety of heating effects, which may range from a sensation of warmth to burns and eventual cataract formation.
S 1 is a vertical, perfectly inelastic, supply curve. This represents 'momentary' supply. In most industries, if a firm was asked to produce a large order immediately, it simply would not be able to do it, regardless of the price offered for the order. Supply is perfectly inelastic in the very short run.
The classic microeconomics supply and demand model shows price on the vertical axis and demand on the horizontal axis. In between them is a downward-slowing demand curve where price and quantity demanded have an inverse relationship. The general concept is intuitive: as goods become more expensive, people tend to demand less of them. For many simple markets, this inverse relationship holds true. If the cost of a shirt doubles, consumers buy fewer shirts, all else being equal. If the shirts go on sale, consumers tend to buy more. There are several problems with the simple supply and demand model, however.
