The hanging mass is attached at the end of the string to provide tension. Wen a horizontal pick is used to pluck the string just at the pulley, apulse is created in the string and travels along it in form of a disturbance. Atimer is started by the pulse created in the wire by the plucking effect. Te timer continues recording the time until the traveling pulse reaches the sensor, wich stops it. Wen the mass attached to the other end of the string is changed, te time the pulse to cover the entire distance of the wire also changes as shown in the table under results section.

Loking at the above graph of travel time against inverse of overhanging mass, i is a straight line graph. Te graph is drawn after converting the time from ms to s. Te obtained graph is a straight line as introduced earlier. Te graph shows that y-intercept is zero considering the line of best fit. Te linear density of the wire can then be found from the graph using the of the graph reveals a crucial trait about properties of waves.

Tis trait is interpreted as displacement. Te displacement caused by waves is described in terms of perpendicular distance that string particles will move from their equilibrium positions. Tis displacement (D) of particles in a string is dependent on time and position at which displacement was observed. Dsplacement is, terefore, afunction of both position(x) and time (t). Bth factors must be known in order for displacement to be determined. Te string under study in the laboratory produced some of harmonic motion.

Tis simple harmonic motion is referred to as sinusoidal wave. I can be observed that the travelling wave is moving at a certain frequency. Te frequency of travelling waves is always the frequency produced at the source of the wave. Tis is because the source of the wave is oscillating at a given frequency which is displayed in the resultant wave. A the wave travels more characteristics become evident. Aong the traits that are evident is the period of the wave. Te period of a gives the interval for each complete cycle of motion.

Te period, o a wave is equal to the inverse of wave frequency. Wile analyzing the graph of sinusoidal waves, aother property of waves comes out. Tis property is the amplitude; a amplitude is the maximum displacement value that an oscillating wave can. ..
