The crowded or loose grains cause the electric current to become stronger or weaker. The current copies the pattern of the sound waves and travels over a telephone wire to the receiver of another telephone. For more modern phones that have a telephone answering service, the sound wave is captured on a recording device which allows for the operator of the phone to playback at a later time.
The denser the medium, the faster sound will travel. Sound travels through air at the speed of 1,115 feet per second, through water at 4,757 feet per second and through iron at 16,404 feet per second. Light travels at 186,411 miles per second in vacuum. In water, the speed of light drops to 139,808 miles per second.
