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.
On a supply cover, the vertical axis shows various price points for the product or industry being depicted. The horizontal axis represents the relative quantity of goods suppliers will produce. To demonstrate the law of supply, a person must increase the supply volume while increasing the price. This requirement dictates that the slope curves upward. Producers in a given industry must compare the opportunity cost of supplying one good against the opportunity cost of supply another.
