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.
1 When all air is removed there is no medium for the sound waves to travel through so no sound is heard. 2  Here is a video demonstrating this concept: MPEG Video (10MB - 1 hour on 56k modem, 1-2 minutes on high speed connection). 3  Radio waves travel like light waves. 4  They can be absorbed, reflected or transmitted.
