ABSTRACT The experiment entitled “Transverse wave: Frequency of Vibration” aimed to determine the frequency of vibration of the string and to study how the frequency of vibrating string is affected by tension and linear mass density . The students prepared the materials and the set-up given and preceded to the experiment proper. The experiment made use of a string vibrator, sine wave generator, and guitar strings. The guitar strings has different linear mass density. The experiment is started with arranging the set-up. Afterwards, the experiment proceeded in determination of the frequency of vibration. The frequencies of vibration of the string not varying the thickness and varying the thickness of the string, as well as, the percentage error were computed. The result yielded a value of 108.748 Hz having 1.138% error for varying tension and 110.260 having 0.236% error for the. Results also revealed that the ice has a latent heat of fusion of 75.3722 Hz with 5.78% error for the varying linear mass density. . Moreover, the one of the hypotheses are both rejected due to sources of errors and non-ideal condition of experiment while the other two were accepted. INTRODUCTION A wave is any disturbance from equilibrium that propagates from one region to another. Most information came to the people in terms of waves. Sound reaches the ear through sound waves, the light reaches the eyes through the visible light waves, and electromagnetic signals reaches the radio station and television sets via radio waves. These examples show that waves move in order for it to be perceived. Through wave motion energy can be transfer from source to receiver without the transfer of matter between two points. These waves that travel through mediums are called mechanical waves. There are two types of mechanical waves in terms of the displacement of the medium. First is a transverse wave which propagates a particle perpendicularly, and longitudinal wave that propagates a particle parallel. If waves are wiggled in a continuous pattern, a periodic wave is created and often called sinusoidal waves, because it follows the shape of a sine curve. Since periodic waves travel certain points, it has its wave velocity. A wave velocity is can be related to a particle velocity where in it is the distance travelled over a period of time. Wave velocity is also the distance travelled, the wave length, over a period of time. The experiment deals with transverse waves. Transverse waves are usually seen in strings and for its velocity, two certain values must be considered. First is the tension of the string and the other one is the linear mass density of the string. Linear mass density is the mass of the string per unit length. These three properties are related to one another in terms of a mathematical equation, ± √ ² ³ , where v is the wave velocity, F is the tension or force and μ is the linear mass density of the string.
