What causes an echo to be heard?
An echo is heard when sound waves bounce off a hard surface and return to the listener's ear after a short delay. This delay is a result of the time it takes for the sound waves to travel to the surface and back. The distance between the sound source and the surface also affects the strength and clarity of the echo.
What wave interactions produces an echo in a canyon?
Sound waves interacting with the canyon walls can produce an echo. When a sound wave hits a wall, it reflects back towards the source creating an echo. The distance between the source of the sound and the reflecting surface determines the time delay between the original sound and the echo.
Why the echo of a sound made by us is not heard in small room?
In a small room, sound waves can quickly bounce off the walls, ceiling, and floor, leading to multiple reflections that can interfere with each other and cancel out the echo. This phenomenon is known as acoustic interference, which can dampen or eliminate the perception of an echo in a small space.
What are two factors that can affect the clarity of an echo?
The distance between the sound source and the reflecting surface can affect the clarity of an echo. The presence of obstacles or sound-absorbing materials near the reflecting surface can also impact the clarity of an echo.
What are two factors that can affect a echo?
Two factors that can affect an echo are the distance between the sound source and the reflecting surface, and the material and texture of the reflecting surface. Both factors contribute to the sound waves' ability to bounce back and create an echo.
What is the minimum distance required to produce a distinct echo in meter?
17.2m

Why do you not get echo at all places?
we do not get echo at all the places because everywhere there cannot be the distance of 17.2m b/w the source of sound and the object.
What is the minimum distance of echo?
Depends on the quality of the sound. The minimum distance to hear an echo will be partly based upon the observers ability to resolve different sounds (i.e. so that they can distinguish between the actual noise, and the arrival of the reflected sound - a little 100 year old lady may not be as good as a 15year old!). This will vary between observers, as their auditory reaction times vary In the perfect Physics world though: Assuming a sharp sound (like a gunshot) the minimum distance (d=vt) to hear distinct echo is 17.2m considering the speed of sound to be 344ms. In general the "minimum echo distance" is always equal to half a wavelength from the reflector.

Where do you find an echo?
Any wall in any enclosed room , hill or obstacle about 17 meters away or more will produce an echo.

How long can an echo last?
The duration of an echo depends on a few factors such as the distance between the sound source and the reflecting surface, the material and shape of the surface, and the acoustics of the environment. Generally, an echo can last anywhere from a few milliseconds to a few seconds.
What are two factors that can affect a echo?
Two factors that can affect an echo are the distance between the sound source and the reflecting surface, and the material and texture of the reflecting surface. Both factors contribute to the sound waves' ability to bounce back and create an echo.
How do dolphins use sound waves?
Dolphins emit high pitched ultrasonic waves that reflect off obstacles. The reflected wave reaches the dolphin and the dolphin is able to estimate the distance of the obstacle. (pulse echo detection)
