An Echo-echo-echo-echo! The answer is Echo
It is still a sound wave.
A P wave reflects atrial depolarization.
Sound is a longitudinal, mechanical wave that requires a medium.
The result of a reflected sound wave is obviously an echo.
The amplitude (The height of the wave) of the wave increases as the sound gets louder.
the strength or volume of the sound wave :)
When a sound wave strikes a smooth hard surface the wave bounces off. This means that the wave is deflected.
reflection
sound wave reflect best off smooth, hard surfaces
That's the incident wave.
An echo is a sound wave that has bounced off a surface
Large obstacles reflects sound waves. If you shout in front of a valley the sound wave travels in all directions and is reflected by an obstacle such as a wall or a cliff.
what is an echo?An echo is the repetition of sound by reflection of sound wave on a hard surface.
The bouncing of a sound wave off a surface may result in an echo being heard.
Compression
sound expands it looks like a tide at the beach it expands until it doesn't disturb the surface of the wave but in sound the sound is unable to be heard
It has to have a hard surface to bounce off of. :)Apex Not necessarily. The reflector is the surface of a medium of greater density than that through which the incident sound travels, and it can be the surface of water, or a density-boundary caused by sharp temperature or salinity differences in the sea.
