Briefly describe the characteristics of sound wave.
Answers
Answer:
Sound cannot travel through a vacuum. This is very much in contrast with the property of light. Another difference which is above the scope of the syllabus is the fact that sound waves are generally longitudinal waves and light waves are transverse waves. But they’re not very different either. Let’s take a look at the characteristics of sound when propagating through air.
Answer:
The sensation felt by our ears is called sound. It is a form of energy which makes us hear. We hear several sounds around us in our everyday life.
We know that sound travels in the form of wave.
A wave is a vibratory disturbance in a medium which carries energy from one point to another without there being a direct contact between the two points.
We can say that a wave is produced by the vibrations of the particles of the medium through which it passes.
There are two types of waves: Longitudinal waves and Transverse waves.
Longitudinal Waves: A wave in which the particles of the medium vibrate back and forth in the ‘same direction’ in which the wave is moving. Medium can be solid, liquid or gases. Therefore, sound waves are longitudinal waves.
Transverse Waves: A wave in which the particles of the medium vibrate up and down ‘at right angles’ to the direction in which the wave is moving. These waves are produced only in a solids and liquids but not in gases.
