because the minimum distance between the us (the source) and the reflector
should be 16.5 cm.
An echo of a wave is exactly the same type of wave as the original wave. An echo is simply the original wave returning to the observer, so if you made a sound (a longitudinal wave of vibrating air molecules), the echo is also sound waves.
Sound is a wave that travels through air and an echo usually occurs when you are surrounded by walls or in a tunnel of some sort. The sound wave that comes back to you has already hit the wall and bounced back so you can hear it again.
Yes. A sound wave was sent from a source which made a noise, it hit some solid object and was reflected back to the hearer, who hears the echo some time after hearing the original noise.
A "tinkle".
When a sound wave hits a surface and reflects back towards its source, it creates an echo. The time delay between the original sound and the echo is determined by the distance between the source and the reflecting surface. The intensity of the echo is typically lower than the original sound due to energy losses during reflection.

The sound waves travel till a solid vertical obstacle, hit it and bounce back, travelling towards you. When they reach you, you can hear the sound you made, but it's several seconds off, the delay depending on the distance the sound had to cover.

Echos are created by the reflection of sound waves from a surface.
The Greek goddess of sound was Echo. She was cursed by Hera after distracting her with gossip. After Echo wasted away for love of Narcissus, she was made into an immortal.
Duncan Heyward thought the terrible sound he heard was made by a panther or other wild animal.
Duncan Heyward believed that the terrible sound he heard was produced by the footstep of a giant.
No, an echo is a reflected sound wave and does not have the ability to speak or produce independent sounds. It simply repeats sounds that are made in its vicinity.

Like a glockenspiel (both are made of wood) but each note has a sort of echo provided by the gourd underneath. It's a really pleasant sound!
