How can microwave travell through walls and objects?
We're guessing that you have no trouble listening to the radio in your basement, or watching TV inside in the middle of your house. The so-called "microwaves" are exactly the same physical phenomenon as radio waves and TV waves. Their shorter wavelength means that they suffer more loss when they penetrate material objects, which is why microwave design engineers (ahem ahem) always try to arrange for clear, unobstructed line of sight for microwave communications. But that doesn't mean that any solid material instantly stops microwaves dead. It just means that they can't penetrate quite as far as FM radio and TV can. The above answer is right , but what i meant is what is the Engineering formulla that claculate the penetration of microwave?
Is a microwave radioactive?
No, microwave ovens are not a source of low-level muclear radiation.Microwaves operate by generating microwave electromagnetic radiation. This radiation acts on the contents of the oven and causes what is called dielectric heating. In this process, molecules (primarily water) in the food try to align themselves with the direction of the electromagnetic energy. As the microwave energy is constantly (and very rapidly!) changing is polarization, the molecules will be quickly moved around. This will add energy to the food, and it will appear in the form of thermal energy, or heat. None of this involves nuclear radiation, low-level or otherwise.
Is red shortest wavelength?
Yes. The longest visible wavelength / lowest visible frequency is the last color you see on the red end of the 'rainbow'. The shortest visible wavelength / highest visible frequency is the last color you see on the violet end of the 'rainbow'. These limits are not exactly the same for every human eye.
What happens to an electromagnetic wave's frequency as it's wavelength decreases?
The product of (wavelength) x (frequency) of any wave phenomenon is alwaysthe same number ... the speed of the wave. So if wavelength changes, thenfrequency must change by exactly the same factor in the opposite direction,in order for their product to remain constant.
What is the wave speed of ultra violet?
The speed of ultraviolet (UV) waves is the same as the speed of light in a vacuum, which is about 299,792 kilometers per second. Ultraviolet waves are a type of electromagnetic radiation that falls between visible light and X-rays on the electromagnetic spectrum.
Can infra red radiation be used to keep food warm?
Infrared radiation, also commonly known as "heat".
What is meant by microwave engineering?
A: Microwave is a branch of electronics involving very hi frequency whereas the basic of electronics does not follows exactly because of it. Special knowledge is required expertise.
Can you blowup a phone in the microwave?
You can't exactly blow it up (as in explode) - but you can destroy the circuitry !
How are microwaves from space detected and what do they tell us about the beginning of the universe?
Microwaves from space can be detected from the use of radio telescopes. Microwaves have been used to test the big bang theory, and this Cosmic Microwave Background (CMB) radiation is a form of microwave that "fills" the universe, that is almost exactly the same in all directions and is not associated with any star or object. The CMB radiation is recognized to be radiation left over from the big bang, or during the early stages of development of the universe.
Why light rays are considered as electromagnetic waves?
Mainly because that's what they are. Exactly the same physical phenomenon as radio, microwave, heat radiation, ultraviolet, X-rays, and gamma rays, but with wavelengths in the narrow range that your eyes can detect.

What has cosmic microwave background radiation?
The CMBR is microwave radiation coming to our Earth with the same intensity (to within one part in 100,000) from all parts of the sky. Its spectrum is exactly that of a black-body -- ie, like that of a glowing object -- at a temperature 2.7 degrees above absolute zero. It is believed to be the remnant of recombination, 377,000 years after the Big Bang. No other hypothesis about our Universe can explain the CMBR other than saying, "It's just there and I don't know why it should be."
A microwave is halfway between the stove and sink and an electric can opener is halfway between the fridge and sink?
So.... what exactly is the QUESTION !
Could the sun emit radiation of many wavelengths?
Yes, that is EXACTLY what the sun always does.The sun emits a near continuous spectrum from the far infrared through visible light through the far ultraviolet. It also emits some low levels of radio, microwave, x-ray, and gamma radiation.
What is the radiation that was created during the big bang?
Exactly what radiation was created during the big bang is still a matter of debate, and conjecture. However, the radiation that was around only 10 -12 second after the beginning is thought to be well understood. It corresponded to an enormously high temperature, and has been steadily cooling ever since. The current temperature is just below four degrees absolute. This translates to radio noise in the microwave region. This was detected about 50 years ago by two engineers who were trying to do something else. The noise has now been mapped in some detail all over the observable universe. It is referred to as the microwave background radiation.
The Benefits of a GE Microwave?
There are a number of benefits to owning a GE microwave, and many of them lie solely in the quality of GE products. The GE name is known the world over for an extreme level of quality, and this type of name recognition doesn't exactly come easily in the world of kitchen appliances. A GE microwave will give you a great amount of style and functionality in your kitchen. You can also commonly find a GE microwave for a fairly decent price at just about any store in the country. This means you are likely to get a high level of quality for a low price.
How can a microwave start a fire?
"Microwave ovens produce electromagnetic radiation of exactly the right wavelength to excite water molecules. When water molecules become excited, they heat up. Since most of our food contains a fair amount of water, we can heat up our food by selectively heating up the water inside the food.Microwave radiation also passes through glass and plastic, which allows it to travel through tupperware and heat up the food inside."found at: http://www.physlink.com/Education/AskExperts/ae379.cfm?CFID=22634899&CFTOKEN=58d5f08b3bb5a2c7-FB925ECB-15C5-EE01-B90E75BCAA249C91
