name an electromagnetic wave with frequency of 100ghz?

Answer 1

100 ghz is about the middle of the EHF(Microwave band) a wavelength of approx. 5mm @ 1,24meV - The 71-76, 81-86 and 92-95 GHz bands are also used for point-to-point high-bandwidth communication links. These frequencies, as opposed to the 60 GHz frequency, require a transmitting license in the US from the FCC, though they do not suffer from the effects of oxygen absorption as the 60 GHz does. There are plans for 10 Gbit/s links using these frequencies as well. In the case of the 92-95 GHz band, a small 100 MHz range has been reserved for space-borne radios, making this reserved range limited to a transmission rate of under a few gigabits per second.

The band is essentially undeveloped and available for use in a broad range of new products and services, including high-speed, point-to-point wireless local area networks and broadband Internet access. Highly directional, "pencil-beam" signal characteristics permit systems in these bands to be engineered in close proximity to one another without causing interference. Potential applications include radar systems with very high resolution. A recent development has been imagers for security applications as clothing and other organic materials that are translucent in some mm-wave atmospheric windows.

Uses of the millimeter wave bands includes point-to-point communications, and point-to-multipoint communications.

Answer 2

These are called millimeter waves (higher frequency than microwaves). Active Denial Technology uses approximately this frequency to create an intense burning sensation at significant distances without actually causing burns.

Answer 3

100 GHZ, is 10^11 Hertz. a wave of this frequency is said to be in the millimeter wave spectrum. these are also know as microwaves. and the wave is said to be EHF that is extremely high frequency. Any wave from 56 GHZ-100 GHZ is said to be in the "W" band of the millimeter or microwave or EHF spectrum. Waves of this frequency are used for communication.

Answer 4

That's an interesting question. 100 GHz radiation has a wavelength of about 3 millimetres, so it's on the boundary between microwave and teraherz radiation. Teraherz radiation is interesting because we didn't know much about it until about two years ago. Shorter-wavelength radiation like infrared and visible is generated and handled by using optical methods; incandescent surfaces, photosensitive detectors, lenses and prisms. Longer wavelength radiation is the province of radio engineering. But it wasn't until we could manufacture microscopic structures like arrays of microscopic dipole aerials and lenses consisting of microscopic honeycomb structures that we could build a teraherz camera. You can do some interesting things like taking a photo of somebody's internal organs, through their clothes, without zapping them with X-rays. You just use the natural teraherz radiation produced by all warm objects. You can see somebody hiding behind a wall. The European Space Agency is researching this field. They want a teraherz camera for night satellite photos. Other obvious uses are airport security and medicine.

Answer 5

haha - love the Barry response!
Here is a link so you can name a lot MORE frequencies

According to this link,
http://imagine.gsfc.nasa.gov/docs/science/know_l1/spectrum_chart.html
100 Ghz (=10^11) is at the upper end of microwave frequencies, so instead of Barry, I might name the wave "amana".

Answer 6

I think that's around Extremely High Frequency, a little below infrared. (A microwave)

Answer 7

Barry the red photon?
