Physics of Microwaves Essay 981 Words4 Pages Physics of Microwaves Microwaves are used in our everyday lives but most most people don't realize that physics plays a large and important part in the simple household item.
Physics of Microwaves Whenever we heat our food we are oblivious to the forces that cause such a thing to occur and we don't fully understand what happens in front of our eyes and how our food really gets heated in such a simple and efficient way. The first thing people need to understand is that microwaves are actually electromagnetic waves.Essay Electromagnetic Theory Of Electromagnetic Field Electromagnetic waves that carry electromagnetic energy is a family of waves based on the frequency and wavelength (Tom and Heather 34). Arranged in order of increasing frequency then we have Gamma rays, ultraviolet radiation, X-rays, Visible light, Microwaves Infrared, and Radio waves.Essay on Physics of Microwaves Magnetrons are also mostly used in microwave ovens and it has changed everything. In 1921 it was first discovered and put into use and as the years continued it improved once again in 1940.

Microwaves are often used in radar, telemetry and microwave ovens. These are also used to transmit telephone conversations Microwaves are good for transmitting information from one place to another place because microwave energy can penetrate through, light rain, snow, clouds, and smoke.
Waves. Electromagnetic Waves - What are Microwaves?. Microwaves are part of the electromagnetic spectrum. Microwaves have wavelengths that are shorter than radio waves. How are Microwaves Used for Communication?. Microwaves have some wavelengths that pass easily through the atmosphere and they are used to transmit information to satellites. Satellite TV and mobile phone (or smartphone).
High frequency microwaves have frequencies which are easily absorbed by molecules in food. The internal energy of the molecules increases when they absorb microwaves, which causes heating.
Microwave radiation can be used to transmit signals, such as those for mobile phone calls. Microwave transmitters and receivers on buildings and masts communicate with the mobile phones in their.
Experiment 4: Refraction and Interference with Microwaves 2 waves formed at the interface. Therefore, because we know that f c n, ( is wavelength) we can conclude that in the refractive region the wavelength is decreased such that 0 n (2) Here, 0 is the vacuum wavelength.
Microwave Ovens Essay 1327 Words6 Pages Like many great science inventions of the past, the microwave oven was stumbled upon during another research project. The man who stumbled upon this great kitchen appliance that we use today, is Dr. Percy Spence, a self-taught engineer who worked for the Raytheon Corporation.
Microwaves are electromagnetic waves with a frequency of about 2.45 GHz and a wavelength of about 12.2 cm; in the electromagnetic spectrum, they fall before infrared light but after radio waves (Heckert 2007). In a microwave oven, microwaves are produced by a device called a magnetron.
The microwave oven is a kitchen appliance that heats and cooks food by heating up the particles inside while exposing it to microwaves from the electromagnetic spectrum. The waves were implemented into the machine where the inventor was experimenting with the it.
Microwaves work by shooting waves called microwaves through food. Microwaves are a lot like light waves, they are wavy patterns of electric and magnetic fields. The wavelength (distance from one field wiggle to the nect) is much longer for microwaves than for light. When the microwaves go through the food, they make the water molecules vibrate.
The microwaves emerging from the transmitter are linearly polarized in the vertical plane, and the receiver is sensitive only to the electric-field component parallel to its axis. Begin by recording the wavelength of the microwaves produced by the transmitter.
How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.
Waves in the electromagnetic spectrum can all travel through a vacuum at the speed of light. The wide range of frequencies and wavelengths of different waves have a variety of uses.
In a microwave there are a lot of different components that make it work, one component that makes microwaves unique the magnetron which was how microwaves were first invented, and the magnetron produces the electromagnetic waves so that they are able to cook food.
