reflects off an object and returns to the listener's ear, creating a delayed repetition of the original sound. Echos are heard when the distance between the listener and the reflecting surface is great enough for the sound to travel and return in noticeable time.

Which wave interaction is responsible for echos?

Diffraction is responsible.


What is the scientific explanation for echos?

An echo is a sound wave that has reflected off a boundary


Do sound waves bend around objects?

Yes, sound waves can bend around objects due to a phenomenon known as diffraction. When a sound wave encounters an obstacle, it can diffract or bend around the obstacle and continue propagating in different directions. The amount of bending depends on the wavelength of the sound wave and the size of the obstacle.


In order to hear a sound even though there is an obstacle between you and the source the sound wave must?

diffract


A bounced sound wave is called?

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.


Is sound transverse or longitudinal in nature?

Sound is a longitudinal wave, meaning that the vibrations occur in the same direction as the wave travels.


why we can hear echo?

Echos are made when sound waves hit against something. A sound wave is usually made by sound squeezing air molecules, forcing them to bounce against each other, thus; creating a wave-like pattern. Echos are usually made in partially enclosed (caved in) areas, such as an arena, because it captures more sound waves, instead of letting them spread out all over. It has a destination... YOU!


When does most diffraction occur in a wave?

Most diffraction occurs when the size of the obstacle or aperture is comparable to the wavelength of the wave. This is because diffraction is the bending of waves around obstacles or through openings, and the extent of bending is influenced by the size of the obstacle or aperture.


What is an incident wave and reflected wave?

An incident wave is a wave that strikes a boundary or obstacle. A reflected wave is a wave that bounces off the boundary or obstacle and travels in the opposite direction.


Occurs when sound waves apparently bend around an obstacle.?

The phenomenon is known as diffraction.


When a wave bends around a obstacle what is it called?

When a wave bends around an obstacle, it is called diffraction.


What occurs when an object causes a wave to change direction and around it?

When an object causes a wave to change direction around it, this is known as wave diffraction. Diffraction occurs when a wave encounters an obstacle or slit that is comparable in size to the wavelength of the wave, causing it to bend around the obstacle. This phenomenon is commonly seen in water waves, sound waves, and light waves.
