Objective: To observe free and forced oscillations of a string. Free oscillations will be observed on a string fixed at both ends by using a weak driving force which varies with time sinusoidally. The waves which come from the movement of the string will result in either produce waves that combine together to double amplitude or cancel out in which cases they are considered resonance or anti-resonance waves respectively. Description: This lab consists of a mechanical wave driver, elastic cord which is hung over a pulley and a weight. The elastic cord is connected to one end of the mechanical wave driver which is flat on the lab table. The other end is pulled and draped over a pulley so a weight can be added to it. We will be using several weights for the experiment and we will need to find out the weight and length of the rope for calculations later in the procedure. Theory:
