S 1 is a vertical, perfectly inelastic, supply curve. This represents 'momentary' supply.

A market demand schedules depicts various quantities of a commodity in the market at different prices in a given point of time. A demand schedule can be graphically represented. The graphical representation of demand schedule is known as demand curve. A demand curve can be drawn either on the basis of an individual demand schedule or on the basis of a market demand schedule.
