Answer:
1. Sound is a energy (mechanical)produced by vibrating objects and sound energy is movement of energy through particles.
2.Space occupied by the substance
3.<u>Propagation</u> of <u>Sound Wave</u> and <u>particles of the medium</u>
4.High-Frequency(Ultrasonic wave)
Explanation:
1.Sound is the form of energy which causes sensation of hearing to our ear.It is produce by vibrating objects. When the objects vibrate(to and fro motion) ,they pushes the particles of medium creating the region of high density called compression .When the particles moves backward ,they creates a region of low density called Rarefaction.This pattern repeats indefinitely.
2.Volume is the quantity of three dimensional space occupied by substances like solid,liquid and gases. The SI unit of volume is
In metric system unit of volume is liter
3. Longitudinal Waves: Waves in which displacement of the medium particles are parallel(in the same direction) to the propagation of wave.
Sound wave is longitudinal wave.Hence its particles moves in the same direction as the wave (energy)travel.
4.Frequency: The number of times sound wave passes a given point in one second.Its SI unit is Hertz(Hz).
Frequency of vibration decides the Pitch of the sound waves producing them.
A sound wave of High Pitch means it is oscillating rapidly(at high speed).These are also called Ultrasonic waves. These have frequency more than 20000 Hz. Human being can't hear ultrasonic waves.
