WebTechnology. Radio waves are radiated by electric charges undergoing acceleration. They are generated artificially by time varying electric currents, consisting of electrons flowing back and forth in a metal conductor called an antenna.. As they travel farther from the transmitting antenna, radio waves spread out so their signal strength (intensity in watts … Web26 mei 2007 · The moving object creates a compression wave in front of its motion. In a gaseous fluid such as air, this compression wave moves roughly at the speed of the particles in the fluid, essentially the speed of sound which shares the same mechanism.
The Bulbous Bow – types, characteristics, and effects
WebA bowed string vibrates and moves in a circular motion that produces the fundamental tone, while the vibration produces overtones like a rippling wave. This complex movement of the string is transmitted to the body by the bridge. The bridge transmits this vibration to the top plate of the violin through two fundamental movements; one in which ...

AM radio waves are in kilohertz (kHz =1000Hz), while FM are in megahertz (MHz = 106 Hz). Microwaves oscillate at gigahertz (GHz = 109 Hz) • Period and frequency are just inverses of each other: Period = 1/frequency Frequency = 1/Period Eg. If something makes four vibrations a second, its freq is 4 Hz.
