How is Bluetooth a modern technological application of physics?
Introduction
Bluetooth was invented in 1994 that replaces cable communications with wireless technology. (Ericsson, 1994) Bluetooth creates a wireless personal area network (PAN) that allows exchange of information among individuals and therefore is commonly used for short-range communication among mobile phones, laptops, PDAs and other portable and fixed devices. (Layton & Franklin, [date unknown])
Physics plays an important role in the functioning of Bluetooth in terms of waves. Waves are important in Bluetooth as microwave is the wave transmitted by Bluetooth and the whole functioning of Bluetooth is dependent on the microwave transmission.
Scientific Principles
Method of wave production
A small Bluetooth chip is inserted into a device, the chip replaces the cables and carries all the information normally carried by cables. Then the device transmits the information at a special frequency to a receiver Bluetooth chip via an antenna (made of copper wiring) attached on to the Bluetooth chip. The wave is produced by the movement of the electrons up and down in the antenna when data is transmitted from the master device. (Freeman, 2001) The Bluetooth chip and its antenna are shown in figure 1.
Method of wave detection
The wave is detected when the data transmitted is successfully received by the slave device. The wave is received by the antenna in the Bluetooth chip of the slave device. (Freeman, 2001) When the wave is detected by the antenna it causes the electrons in the receiver antenna to move up and down and therefore transfer the data.

The Social Impact of Cell Phones
1466 Words | 3 PagesIn April of 1973, a man named Martin Cooper altered the way of communication for the rest of his days and many years to come. He possessed a dream that would better the way we conversed with one another from a distance. Back in those times, the closest thing to “cellular technology” was a car phone made by the AT&A Company but, Martin and his determined Motorola group yearned higher heights and deeper depths for communication- and thus the birth of the first cell phone was in process. Cooper wanted to exceed the limitations of just simple “car conversation”. After consistent tedious hours of production, lasting a several month long period of building, critiquing, and finalizing, the first cell phone was born. The first mobile device was the size of a cinderblock and weighed the equivalence of its worth- a stack of
Radio
1500 Words | 3 PagesRadio-wave technology is one of the most important technologies used by man. It has forever changed the United States and the world, and will continue to do so in the future. Radio has been a communications medium, a recreational device, and many other things to us. When British physicist James Clerk Maxwell published his theory of electromagnetic waves in 1873, he probably never could have envisioned the sorts of things that would come of such a principle. His theory mainly had to do with light waves, but fifteen years later, a German physicist named Heinrich Hertz was able to electrically generate MaxwellÕs ÒraysÓ in his lab. The discovery of these amazing properties, the later invention of a working wireless radio, and the resulting technology have been instrumental to AmericaÕs move into the Information Age. The invention of radio is commonly credited to Guglielmo Marconi, who, starting in 1895, developed the first ÒwirelessÓ radio transmitter and receiver. Working at home with no support from his father, but plenty from his mother, Marconi improved upon the experiments and equipment of Hertz and others working on radio transmission. He created a better radio wave detector or cohere and connected it to an early type of antenna. With the help of his brothers and some of the neighborhood boys he was able to send wireless telegraph messages over short distances. By 1899 he had established a wireless communications link between England and France that had the ability to operate under any weather conditions. He had sent trans-Atlantic messages by late 1901, and later won the Nobel prize for physics in 1909. Radio works in a very complicated way, but hereÕs a more simple explanation than youÕll get from most books: Electromagnetic waves of different wavelengths are produced by the transmitter, and modulations within each wavelength are adjusted to carry ÒencodedÓ information. The receiver, tuned to read the frequency the transmitter is sending on, then takes the encoded information (carried within the wave modulations), and translates it back into the sensory input originally transmitted. Many of the men who pioneered radio had designs for it. Marconi saw it as the best communication system and envisioned instant world-wide communication through the air. David Sarnoff ( later the head of RCA and NBC) had a vision of Òa radio receiver in every homeÓ in 1916, although the real potential of radio wasnÕt realized until after World War I.
Wave Particle Duality Essay
1022 Words | 3 PagesSome physical entities such as light can display some characteristics of both particles and waves. Before the early 20th century, scientists believed that light was in the form of an electromagnetic wave. It wasn’t until the 20th century onwards that scientists found that light has properties of waves and particles. Scientists discovered different properties of light through experimentation and allowed them to determine that light actually has a wave-particle duality.
