The hanging mass is attached at the end of the string to provide tension. When a horizontal pick is used to pluck the string just at the pulley, a pulse is created in the string and travels along it in form of a disturbance. A timer is started by the pulse created in the wire by the plucking effect. The timer continues recording the time until the traveling pulse reaches the sensor, which stops it. When the mass attached to the other end of the string is changed, the time taken by the pulse to cover the entire distance of the wire also changes as shown in the table under results section.Looking at the above graph of travel time against inverse of overhanging mass, it is a straight line graph. The graph is drawn after converting the time from ms to s. The obtained graph is a straight line as introduced earlier. The graph shows that y-intercept is zero considering the line of best fit. The linear density of the wire can then be found from the graph using the formulaFurther analysis of the graph reveals a crucial trait about properties of waves. This trait is interpreted as displacement. The displacement caused by waves is described in terms of perpendicular distance that string particles will move from their equilibrium positions. This displacement (D) of particles in a string is dependent on time and position at which displacement was observed. Displacement is, therefore, a function of both position(x) and time (t). Both factors must be known in order for displacement to be determined.The string under study in the laboratory produced some kind of simple harmonic motion. This simple harmonic motion is referred to as sinusoidal wave. It can be observed that the travelling wave is moving at a certain frequency. The frequency of travelling waves is always the frequency produced at the source of the wave. This is because the source of the wave is oscillating at a given frequency which is displayed in the resultant wave.As the wave travels more characteristics become evident. Among the traits that are evident is the period of the wave. The period of a wave gives the time interval for each complete cycle of motion. The period, of a wave is equal to the inverse of wave frequency. While analyzing the graph of sinusoidal waves, another property of waves comes out. This property is the amplitude; an amplitude is the maximum displacement value that an oscillating wave can
