Demonstration of the Navy Electromagnetic Rail Gun prototype

Sep 22nd

The US Navy’s Electromagnetic Rail Gun that is under development at NSWC Dahlgren in Virginia. This is a prototype to demonstrate the technology of the rail gun for use on the future DDG-1000 class of Navy ships. This clip is from the show FutureWeapons on the Discovery Channel. It aired in April 2007. The show occasionally repeats on the Military Channel (part of the Discovery Channel family). (NOTE – This has nothing to do with the movie Transformers 2.)

Protect Yourself From Cell Phone Radiation, Electrical Appliance Radiation & Electromagnetic Fields

There’s a lot of buzz on whether cell phones emit enough radiation to cause ill health effects. This concern arises because the cell phone is placed close to the head during use. Hence it puts the radiation in direct contact with the tissue in the head.

Cell phones have low-power transmitters in them. Most car phones have a transmitter power of 3 watts. A handheld cell phone operates on about 0.75 to 1 watt of power. The position of a transmitter inside a phone varies depending on More >

Question by stefanied26: various technologies used to observe the universe in all the wavelegnth regimes of the electromagnetic spectrm Describe the various technologies used to observe the universe in all the wavelegnth regimes of the electromagnetic spectrum. your description should include the various types of telescopes.

Best answer:

Answer by jgouldenOrbiting gamma-ray and x-ray telescopes observe the highest-energy portions of the electromagnetic spectrum.

Ultraviolet telescopes (orbiting, airborn, or on high mountaintop observatories) observe the UV portion of the spectrum.

Visible-light telescopes, both ground-based and orbital, are used to observe the visible portion of the spectrum.

Infrared telescopes are used to observe the IR portion of the More >
