So would the laser be be amplified or the laserwould be deflected or the laser neutralised

This is the 7rd sign of the apocolypse.\n\nIf you do this the world will explode and we will all die.

Hi. I think it deals more with the interaction of radiation with particles (or a particle) than with speed. At any non-relativistic speed (less than .1 'c' say) the wavelength would not be infinite or unbounded. Just my opinion.

you either need more information, or this is a trivial problem. \n\ni am assuming the two surfaces of the glass are parallel to each other, so it's not a prism or lens, but a thin flat plate.\n\ntreating it very simply, you could argue that energy is conserved, so the irradiance (which is energy per second per square meter) must be conserved.  the speed of light is fixed in air, so the "per second" part is fixed too.  if the glass surfaces are not angled with respect to each other, then the light leaves the glass taking up the same area that it went in with.  this means the irradiances are the same.\n\nthis is a simplistic physical model, though.  realistically, you will get some reflection at the air-glass interface, reflection at the glass-air interface, and some absorption (both in the air and in the glass).  you need a lot more details about the problem to say anything meaningful though.

First realize that since the beam is passing through something, reflection has nothing to do with it.  The only possible answer is the one that mentions refraction.

None of the above.\n\nIt will repel another positive change,\nattract a negative charge,\nand not interact with a neutral charge.

The only significant difference is the level of energy (and therefore power) that the lasers can emit.\n\nLaser pointers emit very low levels of energy, which is why they won't even make you feel warm when you point them on yourself.\n\nA cutting-edge laser (I take it you mean a modern laser used in factories to cut and/or weld metal) emits quite a lot of energy.  In fact it is enough to give you serious third degree burns.\n\nIf you are talking about weapon-quaility lasers (like in Star Trek), they don't exist yet, but they would require many times the amount of energy of a cutting laser.

The simplest cheapest way to split a laser is with a plate of glass. Shine a laser through it and some with reflect, and some will transmit. Usually most transmits, but you can control the percentage that reflects by rotating the plate until the angle between the laser and the plate is very small. You can get a 50-50 split that way.

Yes.   Many lasers are pumped with incoherent light.   The first laser ever made was a synthetic ruby cylinder about as big as a pencil with a mirror at one end and a half-silvered mirror at the other.   A xenon tube, like a photographer's flash tube, is wound round the cylinder.   Incoherent light from the xenon tube pumps the laser and a coherent beam of red light emerges from the half-silvered end.

i want to make a system that gets mounter to the passenger front bumber of my car, so when im stuck in traffic and some _hole feel he deserves to drive in the emergency lane, the laser will burst a hole in his tire, and give him a reason to be in the emergency lane.  Some issues with this system is the timing of when to fire the laser, how much power the laser would be.  You dont want to accidentally fire at the wrong thing, so these issues must be addressed first.  I think thats pretty innovative.\n\nwhilst working on my M.E. senior design project, my sponsor (an artist) wanted to make a dynamic hologram depicting a full COLOR rainbow..  Yeah, I know...  It made for great jokes the entire year.

Below are some links with some cool diagrams.  I'm not sure if it's specifically what you wanted though.  The second link has some really cool information about spectral transitions in a LASER.

1)Yes, if u change the property of that medium, by adding glycerine in water, or... etc. then the angle of refration would reverse out...  or depending what u want to attain...\n\n2)The velocity increases, due to the fact that the WAVELENGTH increases.\n\n3) There will be total reflection, no refraction above the glass will be seen\n\n4) to get better shine / reflection in stone -  \ntry to measure reflection off marine or other food (spoilage) -\nEPA can do the same with GAs refration,  eyc\n\n5)Fiber Optics communication,, Electro-Optic modulators,, Wave Scattering phenomenon/research   etc

I admire mathematician's concise answers, but in this case some additional explanation may be due:\n\nWhen a wave is partially transmitted and partially reflected the two outgoing waves are shifted in phase from the incident wave. If energy or probability is to be conserved, the difference between the two phase shifts is pi/2 (90°). In this diagram each of the two possible outgoing  beams consist of components from two paths (R=Reflection,T=Transmission):\n\nOutgoing Horizontal: TRR + RRT\nOutgoing Vertical: TRT + RRR\n\nIn the first case the relative phase shift between the two components is 0 and in the second case it's pi (180°) ==> the two components are negatives of each other and interfere destructively.

they use laser to cute it  to be more accurate

To be honest, if I had the choice I would not take it. I think I would prefer to be me. \nIf my physics teacher was some sort of evil genius and only offered me the choice of specifying what type of light he was going to change me to I think that maybe UHF radio waves would be quite good.  90 kg worth of mass converted to energy would certainly be enough to fry my physics teacher and vapourise a significant chunk of the surroundings so that would serve him right and the EMP might destroy just about every piece of electronics on the planet and mess up the ionosphere for years but it should still have less effect on everybody else than x-rays would.

A maser is a device that produces coherent electromagnetic waves through amplification due to stimulated emission. Historically the term came from the acronym "microwave amplification by stimulated emission of radiation", although modern masers emit over a broad portion of the electromagnetic spectrum. When optical coherent oscillators were first developed, they were called optical masers, but it has become more common to refer to these as lasers.

it depends on the type of laser that is being used. In my office we use what is called "intense pulse light". It has a special laser called a "yag". We can usually lighten a tattoo to almost gone. You may not be able to get it to go away totally, but it should be nothing but a faint image. 8 treatments seem to be a bit excessive. I would consult with another doctor

You can not generate true "white" light with a laser.  Lasers are sources of coherent light.  This implies that they are monochromatic (single wavelength or color).  In order to generate white light, you need a broad spectrum (many wavelengths), so you can not use a laser.  However, our eyes can perceive the color white with just a combination of a few colors (red, blue, green).  So a laser system that combines a red, green and blue laser will give you the impression that it is a white laser.
