Examples of a sound wave
What is a sound wave and how does it move?
Sound (in air) is made when air molecules vibrate and move (away from the vibrating source) in a pattern called waves, or sound waves. Sound is a mechanical, longitudinal wave (that moves in all directions) and travels in waves of compressions and rarefactions (expansion) as it successively passes through a medium.
What are sound waves and how do they work?
Sound waves are like light and water waves in other ways too. When water waves traveling long distances across the ocean flow around a headland or into a bay, they spread out in circles like ripples. Sound waves do exactly the same thing, which is why we can hear around corners.
What are some examples of sound waves?
Two examples of sound waves are transverse waves and longitudinal waves. Students can visualize transverse waves as ripples on a pond and longitudinal waves the movements of a slinky. ... Sound waves are created by the vibration of an item, which then produces a pressure wave that displaces the air.
What type of waves make up a sound wave?
A sound wave is a type of pressure wave caused by the vibration of an object in a conductive medium such as air. When the object vibrates, it sends out a series of waves that are interpreted as sound. The vibrations travels at different speeds through different types of mediums and all mechanical waves require a medium through which they can move.

What Is Sound? Sound is a pressure wave which is created by a vibrating object. This vibrations set particles in the sur-rounding medium (typical air) in vibrational motion, thus transporting energy through the medium. Since the particles are moving in parallel direction to the wave movement, the sound wave is referred to as a longitudinal wave.

Discussion Examples Chapter 14: Waves and Sound 14. A brother and sister try to communicate with a string tied between two tin cans (Figure 14–33xx34). If the string is 9.5 m long, has a mass of 32 g, and is pulled taut with a tension of 8.6 N, how much time does it take for a wave to travel from one end of the string to the other?

(b) Here we are given information that lets us calculate the wave speed. The ‘sound’ took 3:90 10 4 seconds to travel 1:5 mso the wave speed must be v= d=t= (1:50 m)=(3:90 10 4 s) = 3846 m=s. The wave speed in this type of material is given by v= q Y=ˆthough so we can rearrange this to nd Y = ˆv 2.

The energy in a sound wave is called amplitude. Sounds with high amplitude are made by objects that vibrate with a lot of energy. Amplitude is the loudness of sound. The louder a sound is, the higher its amplitude. The higher the amplitude of a sound wave, the more energy it has. As a rocket blasts off, high-amplitude sound waves fill the air.

A wave is a periodic disturbance that spreads out from a source and carries energy with it. There are two types of waves mechanical and electromagnetic. Mechanical. Examples -- sound waves, water waves, etc. Require medium for transfer; cannot be transferred through a vacuum . The speed of the wave depends upon the mechanical properties of the ...

A transverse wave appears like Figure 1 below. It appears like the waveform that was formed by the Wave Machine at sound Station 2. The straight line going through the center of the symmetrical wave is the zero axis. The points where the transverse wave crosses the zero axis (A, C, E) are the nodes.

Examples: light, ocean waves. longitudinal wave (or compressional wave): compresses and decompresses the medium as it travels through. Examples: sound, pressure. wavelength (or period): the length of the wave, measured from a specific point in the wave to the same point in the next wave. Symbol = λ (lambda); unit = distance
