A reflected sound wave can be one of two things, an echo or a reverberation. Reverberation happens when sound bounces off surfaces and reaches back to the ear within 0.1 seconds. Echoes happen when sound waves bounce back to the ear after more than 0.1 seconds.
The top of a sound wave is called the crest. It corresponds to the point where the amplitude of the wave is highest.
When a sound wave hits a surface, it may bounce back rather than pass through it. This bouncing of sound waves off a surface is called sound reflection. The angle at which the sound wave hits the surface affects how it reflects.
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.
It is called frequency
