What is sound wave PPT?
The sound wave is a longitudinal wave. • Each cycle of the sound wave includes one compression and one rarefaction. If, for example, a speaker vibrates back and forth at a frequency of 500 Hz, then 500 compressions, each followed by a rarefaction, is generated every second.

What are the sound waves?
Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner. Do not be misled – sound waves traveling through air are longitudinal waves.
What are sound waves Slideshare?
Sound waves are produced by the vibration of material objects. A disturbance in the form of a longitudinal wave travels away from the vibrating source.
How do we hear sound waves?
The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. The bones in the middle ear amplify, or increase, the sound vibrations and send them to the cochlea, a snail-shaped structure filled with fluid, in the inner ear.
What are the properties of sound PPT?
Properties of sound
- SOUND AND ITS PROPERTIES At a Glance.
- Properties of Sound Pitch Intensity Loudness Quality.
- Pitch Note Frequency (Hz) This refers to the highness or lowness of a sound.
- Loudness This is a subjective interpretation that varies from person to person.
What are the properties of sound wave?
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave indicates the distance that wave travels before it repeats itself.
