Classification of Sound. In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology andpsychology, sound is the reception of such waves and their perception by the brain. Sound is a longitudinal, mechanical wave.
Sound, like all longitudinal waves, requires a medium (material) to move through. Sound cannot travel in space, for example. Sound waves contain high density compressions (peaks) and low density rarefactions (troughs). They have wavelengths (the distance peak to peak) and frequencies (the number of waves per second). classification of sound in physics ppt
Title: The Physics Of Sound 1 The Physics Of Sound. Chapter 9 (Turn on your speakers) 2 Sound is made when something vibrates. The vibration disturbs the air around it. This makes changes in air pressure. These changes in air pressure move through the air as sound waves. 3. Feeling Sound. When something is making a steady sound then it NCERT CBSE Notes for Class 9 Science physics Chapter 12 SOUND 1. Production of Sound. Such waves are called longitudinal waves. There is another kind of waves called transverse waves. In these waves the particles oscillate up and down perpendicular to the propagation of the direction of disturbance. Physics Sounds. Diffraction of Sound Sound waves bend or diffract around corners or barriers like doors and walls. Characteristics of musical sounds Note basic element of music 1. Pitch highness or lowness of the note 2. Intensity loudness of the note 3. Rhythm repeating pattern of beats and it keeps the time to the music 4. classification of sound in physics ppt Characteristic& Classification of Sound 1. GOVERNMENT ENGINEERING COLLEGE BHARUCH PHYSICS Classification and Characteristics of sound Nakrani Pratik R. 2. PowerPoint Presentation: Amplitude is the maximum distance the particles in a wave vibrate from their mean positions. Amplitude controls the volume and intensity of sound. The amplitude of a longitudinal wave is determined by the closeness of the longitudinal waves. The closer the longitudinal waves and the farther the rarefaction lines. Jun 07, 2013 Mechanical Waves Mechanical waves are disturbances in matter that carry energy from one place to another. Usually require matter through which to travel The matter a wave travels through is called a medium. Medium can be a solid, liquid, or gas Some waves can travel through spacewith no medium!
