A stretched-out area of a wave is called a rarefaction.
A bounced sound wave is acalled an echo. You can hear these echos when you yell into a cave or a crevasse or an abyss.
The height of half a sound wave is called the amplitude. It represents the maximum displacement of the wave from its rest position and is a key factor in determining the loudness of the sound. In a graphical representation of a wave, the amplitude is measured from the center line (equilibrium) to the peak (or trough) of the wave.
Regions in a sound wave where particles are farthest apart are called rarefactions. In a sound wave, these rarefactions alternate with compressions, where particles are closest together. Together, these alternating regions create the wave’s propagation through a medium.
The shock wave is called SONIC BOOM.
The disturbance that travels through a medium as a compressional wave is called a longitudinal wave. In this type of wave, the particles of the medium move parallel to the direction of the wave's energy propagation. Sound waves are a common example of longitudinal waves.
The stretched out part of a wave is called the wavelength. It is the distance between two corresponding points on a wave's cycle, such as from peak to peak or from trough to trough.
If the wavelength of a sound wave increases, the frequency of the wave decreases. This means that the pitch of the sound would decrease. Essentially, the sound wave becomes stretched out, resulting in a lower pitched sound.
The top of a sound wave is called the crest. It corresponds to the point where the amplitude of the wave is highest.
The reflected sound wave is called an echo.
A sound wave of high pressure is called a compression or a peak in the wave's amplitude. These high-pressure regions correspond to the portions of the wave where air particles are densely packed together.
The intensity of a sound wave is called sound intensity. It measures the amount of energy transmitted by the sound wave per unit area. Sound intensity is measured in decibels (dB).
When a sound wave bounces off a surface, it is called an echo.
The distance from crest to crest in a sound wave is called the wavelength. It represents the physical length of one cycle of the wave and is directly related to the frequency of the sound wave.
Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
The reflection of a sound wave is called an echo. When a sound wave encounters a hard surface, it bounces back and can be heard again, creating an audible reflection known as an echo.
It is called an echo.
A bounced sound wave is acalled an echo. You can hear these echos when you yell into a cave or a crevasse or an abyss.
