"A universal mirror would serve a variety of purposes. Installed on aircraft, boats or satellites, a universal mirror would makes these objects easier to track with radar. When radio waves ordinarily hit these objects, they scatter in many different directions, and only a few radio waves bounce back to the original source of the radar.With a radio universal mirror, all the radio waves would bounce back to their original source, making them much easier to detect and giving the object a much larger radio profile"]]>Jul 20th 2009 7:19AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Thanks a lot!]]>Jul 20th 2009 8:25AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/See Wikipedia: http://en.wikipedia.org/wiki/Retroreflector]]>Jul 20th 2009 9:31AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 6:51AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 10:26AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 7:03AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 7:09AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/
Which seems to beg the question of why can't a field-array of tiny corner mirrors be made and what would the effect of that be?]]>Jul 20th 2009 7:14AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/
Moreover, you can buy devices with similar function. It's called Retroreflector, check it out in wikipedia. ]]>Jul 20th 2009 8:50AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/
If you're going o talk about something like this, at least give us a basic understanding of WHAT IT IS!]]>Jul 20th 2009 2:19PMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/
?

That doesn't sound right. What about, "Angle of incidence equals angle of reflection?" Perhaps I don't understand what the author means.]]>Jul 20th 2009 7:09AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 2:23PMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 7:21AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 8:01AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/
I thought mirrors reflected light, not objects.

"If a mirror reflected at 90 degree angles, wouldn't that mean you would never be able to see yourself in it?"

It's 90 degrees from the angle of origin, which doesn't apply when you're directly in front of the mirror.]]>Jul 20th 2009 9:41AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 10:30AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 11:56AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 7:34AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 8:36AMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/

Although the only light you can see is that which enters your pupils, so therefore only the light that reflects from your pupils is what you'd be able to see in the mirror. Of course people's pupils are dark (because the pupil is the hole into which light enters your eyeball), so the only light that reflects is either that reflecting off the cornea or the light reflecting off the retina.

Yeah, the mirror would look pretty black, for the most part.]]>Jul 20th 2009 1:29PMhttp://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/http://www.engadget.com/2009/07/20/universal-mirrors-more-useful-less-fun-than-carnival-mirrors/Jul 20th 2009 6:23PM
