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.

A market supply curve is a line drawn on a graph that represents the supply of a particular good or service. It is often used in conjunction with a demand curve. The point at which the supply and demand curves meet is considered the equilibrium price, or the perfect price for supply and demand of that product.
