A vibrating object producing a series of compressions (C) and rarefaction (R). ![]() When the vibrating object moves backward, it forms a region of low pressure called rarefaction (R). It is a region where particle are far from each other. To exemplify, w hen a vibrating object moves forward, it pushes and compresses the air in front of it, forming a region of high pressure called compression (C).Ĭompressions are the regions of high pressure and density where the particles are crowded and are represented by the upper portion of the curve called crest. It is a region where particles are closer to each other. Longitudinal waves further consist of two regions: We can also say that in this case, particles of the medium oscillate along the direction of propagation of the wave. It is that wave in which particles vibrate to and fro. It is the wave which can travel through a medium as well as through vacuum. It is that wave which needs a medium to travel. When we throw a stone in any water body, like pond or lake, we see ripples and this stone hinders the particles of water due to which disturbances occur in a wide range at a regular interval of time. Wave is defined as a periodic disturbance in a medium (air, water, and gas) that transfers energy from one particle to another. A music player sound like guitar, violin, etc.There are different types of sounds which we can hear, written as follows: While some of these sounds may be pleasant and soothing, some could be annoying. Also, we hear our favourite song playing in the iPod. We have also heard a variety of sounds from sitar, violin, veena, ringing of temple bells, chirping of birds, vehicles honking in traffic, dogs barking, pressure cooker whistling, crackers bursting, rattling and breaking of objects. A stretched rubber band when plucked, vibrates and produces sound. All sounds are a combination of pure frequencies. These vibrations create sound waves which move through medium such as air and water before reaching our ears. We can also say that it is a form of energy and it comes from vibrations. Sound is a form of energy that produces sensation of hearing. ![]()
