how do microwaves work electromagnetic spectrum

The electromagnetic spectrum is just a name Of a range of radiation, let me tell you what they are. The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. Microwaves are the highest-frequency electromagnetic waves that can be produced by currents in macroscopic circuits and devices. But what are microwaves and how do they work? Radio: Radio waves have the longest wavelength in the electromagnetic spectrum (up to a football field long).They are invisible to our eyes. Radio waves, Microwaves, Infra-red Radiation, Visible Light, Ultra-Violet, X-rays, Gamma Rays. Microwaves are sandwiched between radio waves and infrared light on the electromagnetic spectrum. Electromagnetic radiation can be useful as well as hazardous. Advanced; Basic; The Electromagnetic Spectrum. Heating food in just second, Microwaves do that. Because of microwave ovens, microwaves have become a household word. But what are those waves really doing in there? Electromagnetic Radiation is all around us and we use it all the time! - Security: Allows airport security to observe the internal contents of objects and luggage using airport Be it radios, WiFi, the sun and even seeing colour, it is an integral part of how our world works. The spectrum of visible light is 7 colours (red - violet). Access Free Electromagnetic Spectrum And Telescope Webquest Answer Key Electromagnetic Spectrum And ... How do radio telescopes work? The behaviour of an electromagnetic wave in a substance depends on its frequency. Cell phone waves are shorter than radio waves, but longer than microwaves.. Microwaves: Also invisible, we use microwaves to heat our food quickly. The electromagnetic (EM) spectrum is the range of all types of EM radiation.Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. These types of rays include radio waves, microwaves, infrared light waves, ultra-violet rays, X-rays, and gamma rays. ... How do mobile phones work? The electromagnetic spectrum—a closer look. The most common type of radar works by sending out bursts of microwaves, detecting the "echoes" coming back from the objects they hit, and using the time it takes for the echoes to come back to work out how far away the object is. Their wavelength is usually a couple of centimetres. In addition to radio waves and microwaves, the EM spectrum also includes infrared radiation, visible light, ultraviolet, X-rays and gamma rays. Here in this microwaves lecture we will discuss what are microwaves, various applications of microwaves and also the microwaves electromagnetic spectrum. Photo: Diagram of electromagnetic spectrum courtesy of NASA.. All the different kinds of electromagnetic radiation are essentially the same "stuff" as light: they're forms of energy that travel in straight lines, at the speed of light (300,000 km or 186,000 miles per second), when electrical and magnetic vibrations wiggle from side to side. This spectrum actually extends beyond both red and violet (invisible). So, microwaves are just high-frequency electromagnetic waves, and your microwave oven creates a high-intensity electromagnetic field to cook your food. 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). Electromagnetic radiation or EM radiation is a noticeable part of the spectrum. Microwaves are electromagnetic rays with a frequency range of 0.3 GHz to 300 Ghz. Appliances that work on electricity produce a toxic EMF (electromagnetic field) around 60 hertz. The electromagnetic energy carries the data using radio waves and is responsible for the creation of some truly innovative devices, which it is now hard to imagine living without. The electromagnetic (EM) spectrum refers to the range of all types of EM rays.
