The radio is a very important device in our daily living. Although most people do not know what it takes to keep radios working. In a radio there are many elements needed to keep a radio working frequency, resonance and radio waves are all elements needed to power a radio. Frequency means the number of incidence of a repeating event per unit of time. Frequency sends sound signals on a radio wave. FM also stands for frequency modulation. FM and AM are the main chiefs of sending music and words. Frequency receives the name temporal frequency. FM is better than AM. For example, FM is free of static from interferences that affect AM broadcasts and the music of f frequency modulation sounds better. One of the main uses of frequency modulation is radio broadcasting. In radio broadcasting sound signals from two microphones of a stereo record and are then sent out on the radio wave. FM stations send programs such as music and broadcasting. The website says “In frequency modulation, the frequencies of the radio wave is made higher or lower to correspond with the vibration of the sounds to be sent.”(Wikipedia Contributors pg.1) Hertz, originally named after the German physicist Heinrich Hertz is known as an important part a radio refers to the SI units of frequency. An example, one hertz mean that an event happens once per second.
Resonance means the certain way which a system moves at larger amplitudes at some frequencies than others. Resonance was originally discovered by Galileo Galilei. The response of resonance, especially for frequencies far from the resonant frequency depends on the detail of physical system and usually not identical to the resonant frequency. Television is an example of resonance which happens when the incomi...

...signal. The park was thought to have very good because outside.
Results, In Krystal’s house the signal was good because a man was heard speaking, at Rosa’s house there was no signal at all just static. At Kiest Park the radio worked very well and the channels were very good. Conclusion, Results about Krystal’s house were correct because in the radio a voice was heard just as predicted. Results about Rosa’s house were wrong because all that was heard was static and no signal at all. Our results about Kiest Park were right because the radio receive very good signal and Spanish channels were heard.
Frequency, Resonance and Radio Waves are all elements need to power a radio. In a radio there are many elements needed to keep a radio working. Although know one know what it takes to keep the radio working .The radio is a very important device in our daily living.

AM Radio Design Essays

- Objective: The objective of this lab is to design and AM Radio. Introduction: Am radio uses Amplitude Modulation (AM), which works by varying the strength of the transmitted signal in relation to the information being sent. When you tune into an AM radio station, for example 1560 on the AM dial the transmitter’s sine wave is transmitted the data at 1560,000 hertz. What this number essentially means is that the sine wave repeats every 1560,000 times per second. The data is modulated onto the carrier wave by changing the amplitude of this sine wave....   [tags: Engineering Radio Design ]

Magnetic Resonance Imaging Essay

- Magnetic Resonance Imaging In 1944, Isidor Isaac Rabi was awarded the Nobel Prize for Physics for his resonance method for recording the magnetic properties of atomic nuclei. This method was based on measuring the spin of the protons in the atom's core, a phenomenon known as nuclear magnetic moments. From Rabi's work, Paul C. Lauterbur and Peter Mansfield were able to research into magnetic resonance imaging (also known as nuclear magnetic resonance, NMR) and were awarded the Nobel Prize for Medicine in 2003....   [tags: Papers]

Magnetic Resonance Imaging Essay

- The Faces Behind the Discovery of Magnetic Resonance Imaging Isidor Isaac Rabi He won the 1944 Nobel Prize in Physics for his "resonance method for recording the magnetic properties of atomic nuclei." He was the one to discover that protons have magnetic moments and that they precess around an external magnetic field. His experiments (on nuclei) revealed the jump between energy states of the proton when resonated with radio frequency waves. Felix Bloch & Edward Purcell Both men independently took Rabi's experiments to the next level - condensed matter....   [tags: MRI]

How Radios Work Essay

- Radios are the most common wireless item in existence and are in most homes. We use them for entertainment, communication, as an information source, or even just back ground noise. For many of us radios are almost a necessity, but how much do we know about how they function. Antennas are one of the key pieces to a radio. Antennas come in a variety of shapes and sizes; they vary from large arrays to a small wire. Much of this variance is based on the broad use of radio waves and practicality; for instance you wouldn't use an antenna from a small radio to send a signal to a satellite....   [tags: radio]

The Radio Frequency Identification Technology Essay

- This project gives an overview of the radio frequency identification technology and the limitations of the usage of RFID technology. Radio Frequency Identification is the wireless technology that uses radio waves to identify objects within its proximity range. This process involves tagging an object to a transmitter which will emit a burst of information including identification of the tag. The identification process and the various components involved in the transmission, identification and receiving of the radio waves are discussed....   [tags: RFID, Radio-frequency identification, Wireless]

Radio Frequency Identification Essay example

- RADIO FREQUENCY IDENTIFICATION Introduction RFID is a technology which enables detecting and identifying objects using electromagnetic radio waves. This is processed through exchange of information between a reader and a tag being attached to the object that includes the data associated with the object. This can be used to detect and classify vehicles, animals, patients, shipment goods and airline baggage. [1] RFID technology involves two main components, they are transponders which are also known as tags or labels, contain the relevant information about the object and other the interrogators, also known as readers or transceivers, that extract the data from the tags....   [tags: Technology, Electromagnetic Radio Waves]

Radio Frequency Identification (RFID) Essay

- The innovation of the RFID chip or the Radio Frequency Identification has been a critical piece of technology that has been around since the early/mid 20th century (est 1938). Functions of a radio frequency identification (RFID) tagging system involves a tag and a reader. When scanned, the antenna within the tag picks up the radio wave and sends a response back to the reader. This technology is being used for both short range and also long range identification, in the short-range identification category, this innovation is used in practical applications like credit cards (pay wave, tap and go ect...), animal identification (domestic pets, farm animals)....   [tags: Radio Frequency Identification]

Radio Frequency Identification (RFID) Essay

- Radio Frequency Identification (RFID) Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader....   [tags: microchip radio waves identification]

Radio Waves Essay

- Radiowaves are the oscillations of magnetic waves by varying the modulation to generate different signals which can be converted into information such as sound, video, or digital communication. As these waves pass through a conductor, an alternating current is generated and this can be converted into usable information. As one could see from the picture above, radio waves are the the electromagnetic waves with wave lengthes between 1mm and 10 Mm. This converts to a frequency range of 300Ghz to 30Hz, respectively....   [tags: physics radio wave]
