Why does it make a noise when you clap?

When you clap your hands, you displace (or move) the air particles between and around your hands. This creates a compression wave that travels through the air (much like it did in the water). The faster the tines move, the less time there is between each compression, causing a higher-frequency sound wave.

Why does it echo in an empty room?

An echo is going to occur in a room when sound waves are reflected back. After moving your things out of a house, you might notice that there is a strong echo in the empty room due to the sound waves reflecting off of the walls. These sound waves are capable of bouncing off of hard and smooth objects.

Can echo happen in closed room?

Sound will echo in an empty room because if there is nothing to stop the sound from reflecting between hard surfaces, such as the walls, windows, ceiling, and floor . However, the sound will continue to bounce between the hard reflective surfaces until it has lost all its energy.

What causes an echo?

The sound waves left your mouth, traveled through the air, hit a hard surface, such as a wall, and then bounced back again, causing you to hear the sound again. An echo is made by sound waves bouncing off a hard surface. The sound waves are typically absorbed before they hit something hard that they can bounce off of.
