What happens to a sound wave when it is reflected off a wall as an echo?
When a sound wave is reflected off a wall as an echo, it bounces back and reaches our ears after a short delay, creating a repeated and fainter version of the original sound.
How does an echo occur?
Sound can bounce off hard surfaces, like light can off bright surfaces. A sound starts and the sound bounces, the sound then bounces off another wall and another and so on. When it bounces it splits into all the directions its side of the wall (if you imagine a protractor against the wall the sound will travel in all angles on that side of the wall. Every time it bounces the sound gets quieter as the energy is lost. The more hard surfaces in a room the less energy is absorbed by the surface. Therefore the reason this does not work in your house it because you may have carpets, pillows on chairs and sofa's.
What is it called when a sound wave bounces off a surface?
When a sound wave bounces off a surface, it is called an echo.
When a sound bounces off a surface it's called?
When a sound bounces off a surface it's called an echo. An echo is the reflection of sound waves off surfaces.
How does sound bounce off walls?
Sound bounces off walls due to the reflection of sound waves. When sound waves hit a wall, they bounce back in the opposite direction, creating an echo or reverberation effect. This happens because the wall's surface is hard and smooth, causing the sound waves to reflect off of it rather than being absorbed.
What do you hear when sound bounces off a smooth surface and is heard more then once?
An echo.

Sound bounces off walls due to the reflection of sound waves. When sound waves hit a wall, they bounce back in the opposite direction, creating an echo or reverberation effect. This happens because the wall's surface is hard and smooth, causing the sound waves to reflect off of it rather than being absorbed.
How do you produce an echo?
Imagine a pool of water. If you dropped a rock in the water you would cause ripples that would travel out evenly in all directions. When one of those ripples hits a wall, you can see that the ripple bounces off the wall. Sound works the same way. Sound is basically just ripples in the air (vibrations). When a sound vibration hits a wall it bounces back much like the ripples in water. * When you hit something and waves travel through the air to your ears. Sometimes sound reflects again.
What is the sound wave that bounces of a surface?
The sound wave that bounces off a surface is called an echo. It is created when sound waves reflect off a surface and return to the listener's ear after a noticeable delay.

Bouncing of a wave off the surface of a substance?
When a wave bounces off a surface, it undergoes reflection. The angle at which the wave hits the surface is equal to the angle at which it bounces off. This phenomenon follows the law of reflection and is commonly observed in various situations, such as light reflecting off a mirror or sound reflecting off a wall.
Why do people often hear echoes in the mountains?
People often hear echoes in the mountains because the sound waves produced by their voice bounce off the mountain walls and reflect back to them. The large, flat surfaces of the mountains act as natural reflectors, causing the sound waves to reverberate and create an echo effect.
