E=mc^2 \nEnergy = mass * (speed of light)^2, c = the speed of light (approx. 186,000 miles per second).

Light does not intend to travel at the speed of light\nLight travels at a certain speed, it actually does not know its speed.\nWhen scientists measured this speed they found it 299 792 458 m / s or about 186000 miles per second \nso they make it fixed term, refereed as "the speed of light", used it in other physical equations...\nthen it "speed of light" became a famous term. \nBut Light still does not know that they called its velocity as the light speed..\nAnd I think it will not know!

A digital tachometer generally uses a laser light to detect rotations and calculates the rpm. it uses the principle of reflection of light from a surface. the rotating shaft / teeth has got markings on surface. the device detects the interval between reoccurance of same mark/blank space and calculates the rpm.

KNOWN:\nf = 3.2 x 10^-2 Hz\nc (ie speed of light) = 3.00 * 10 ^8 m/s\n\nFIND L (AKA wavelength)\nL m = c m/s  /  f Hz\n= 3.00 * 10 ^8 m/s  /  3.2 x 10^-2 Hz\n= 9 375 000 kilometers\n\nAre you sure its 10^-2 Hz? That seems unlikely

La detectacion de luz ,como photon o como onda, depende del typo o metodo de experimento para explorar la naturaleza de la luz. La luz exhibe la characteristica de honda en experimentos de diffraccion e interferencia y exhibe characteristicas de particula en experimentos de ionizacion de atomos con radiacion de varias energias. La luz se mueve en linea recta a menos que es reflejada o desviada por el medio atraves cual viaja. La luz que proviene de estrellas y galaxias distantes provee informacion soble la velocidad de esas estrellas y galaxias porque la luz como onda es cambiada como es cambiado el sonido de un tren qhe primero se aproxima y despues se aleja. ( vea terminos como "red-shift" and "doppler effect") El sonido aumenta cuando el tren viene y despues mengua cuando el tren se va.

It takes an infinite amount of energy to reach the speed of light, so the quick answer is "You can't".\n\nIf you are traveling at CLOSE TO the speed of light and you turn on your lights they will appear (to you) to create cones of light that travel at light speed relative to you.  If you measure the speed of the light, you will get c (approx 300,000 k/sec).  To you, the light will appear to be traveling 300,000 k/sec faster than you are.\n\nAn observer who is not moving (one who see's you as traveing at nearly light speed) will also see the light as traveling at speed c, but he will see it as moving only a little faster than you are.\n\nHow can this be?  It happens because of something called "time dialation/compression" (see the Theory of Special Relativity).  The "seconds" measured by you (in the car) are MUCH longer than the seconds measured by the motionless observer.  That's the magic of special relativity.\n\nThis is confusing stuff.  If you want to really understand it, look up special relativity and read carefully.

Two observers with different frames of reference will measure time and distance differently in such a way that the speed of light is the same in all frames of reference.  Try this site and see if it helps.\n\nhttp://www.glenbrook.k12.il.us/gbssci/phys/Class/relativity/reltoc.html

*\nThe time-honored phrase "faster than the speed of light" might have to be reworked, thanks to the work of a Danish physicist.\n\nBy shooting a laser beam of light through a super-cooled glob of a kind of optical molasses, Lene Vestergaard Hau and her team at the Rowland Institute for Science in Cambridge, Massachusetts, were able to slow the speed of light down to just 38 miles per hour -- not even fast enough for the slow lane of a freeway.\n\nBy contrast, the normal speed of light in a vacuum is about 186,000 miles per second -- 20 million times as fast.\n\n"I would probably not call it God-like, but I would probably say ... we are tampering with nature in a very peculiar, very bizarre way," Hau says.\nlight maze\nHau points to an intricate maze of mirrors, part of the slowing process  \n\nThe research, conducted at the Rowland Institute and Harvard University, was reported in Thursday's issue of the journal Nature.\n\nThe substance that slows the light, called Bose-Einstein condensate, is a microscopic glob of atoms slowed to almost absolute zero -- 459.67 degrees below zero Fahrenheit, the lowest temperature theoretically possible.\n\nResearchers believe that it may be possible to slow the speed of light even further, by a factor of 1,000.\n\n"A human could move faster than that" says Stanford University's Steve Harris, who participated in the project. "But a human couldn't move through a Bose-Einstein condensate, I'll tell you that."\n\nResearchers believe learning how to slow light could eventually have a number of practical applications -- improving computers and communications devices, making television displays and laser light shows more vivid and creating better night-vision goggles.

The speed of light pertains to E&M waves... You can have a wave on a rope for example... it will not be travelling at the speed of light.  To generalize, just state it as 'velocity'\n\nwavelength = velocity/frequency\n\nfor units in this case, x millimeters = (y millimeters/second)/(z cycles/second)

there is a company called schrodinger, or something close t o that.\nthey make lasers measureing tools for the semiconductor and other industrues. they are in massachusetts.

Yes the headlights will work!!  Einstein's theory of special relativity explains that space and time "dilate" as the observer approaches the speed of light so that the observer will ALWAYS be able to "measure" the speed of light to be 300 million meters per second no matter how fast he is traveling.

This page gives a very nice table listing who, when, how, how accurately the speed of light has been measured including the first time when Olaus Roemer did it in a really neat way 330 years ago!\n\nhttp://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/measure_c.html
