The tin can telephone could work since it is able to harness the mechanical wave from air (sound that coming out of our mouth), and transfer it through the string to the can on the other side. As for any physical system, there will be attenuation in the wave energy, so the range of the telephone is limited.

Likewise, people ask, do Cup phones actually work?

The key is to make sure that the string is tight between the two cups, and this normally means that the distance is limited and the two people have to be connected to each other by a straight line. But as long as the string is tight, it works. It is also a great way to understand how telephones and radio work.

Also Know, what kind of string do you use for a tin can phone? 1) Materials: two tin cans that are identical in terms of size and shape, 18 gauge copper wire, aluminum wire, steel wire, and nylon string, a tape recorder, paper, and a pen. 2) Drill a small hole in the bottom of the cans.

Thread one end of string through the bottom of each cup.

What type of wave is sound?

There are two types of waves: Longitudinal waves and Transverse waves. Longitudinal Waves: A wave in which the particles of the medium vibrate back and forth in the 'same direction' in which the wave is moving. Medium can be solid, liquid or gases. Therefore, sound waves are longitudinal waves.

How does the sound travel?

Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. Sound can move through the air, water, or solids, as long as there are particles to bounce off of.

Can and a string telephone?

The highly similar acoustic tin can telephone, or 'lover's phone', has also been known for centuries. It connects two diaphragms with a taut string or wire, which transmits sound by mechanical vibrations from one to the other along the wire (and not by a modulated electric current).

Can sound travel through strings?

If the string is kept tight, the sound waves will travel. If the string is loose, the sound is less. This is because the lose string causes the vibrations to travel all around rather than directly down the string.
