Abstract
Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard. It is produced when something vibrates causing its the medium (water, air, etc.) around it to vibrate as well. In common everyday speech, speed of sound refers to the speed of sound waves in air. Sound travels faster in liquids and non-porous solids than it does in air. In this experiment, velocity of sound in solid, liquid and gas were determined.
Introduction
The wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats. It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings, and is a characteristic of traveling waves and standing waves, as well as other spatial wave patterns. Wavelength is commonly designated by the Greek letter lambda. Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In the experiment, the group should be able to achieve the following objectives: (1) To verify about the relationship of Frequency of sound and its wavelength, (2) to determine the speed of sound by means of resonating column, (3)and to determine the velocity of sound in a solid using a vibrating rod.
Theory The speed of sound is dependent on the medium through which
