how many phase can light propagate?

Greetings,\n\nKinda outta my league, but perhaps the link I posted can be of some use to you.\n\nDiscover had an article last year about a couple of inflation cosmology theorists who believed the speed of light, while constant now, was not constant in the very early universe, it was in fact slower.  Not sure about all that, but thought you might want to go digging for the article.\n\n-matt

OK, this question doesn't make sense, for two reasons:\n\n1.) Colors, by definition, are at different wavelengths. If the beam has 2 color components, each component would have it's own wavelength.\n\n2.) Your question at the end isn't a proper sentence, and is leaving a necessary part out.

yes why not ,light can pass through water        the answer is as follows    except opaque medium light can pass through any medium  but light cannot pass as much fast as in the air medium because acc:theory of huygens light can move fast in rarer medium than in denser medium

The wave length is the distance between two  consecutive points which are in same phase.\n\nThe wave pattern repeats itself after one wavelength.\n\nThus we can consider this as one cycle of operation. \n\nOne cycle corresponds to 2pi radian or 360 degree.\n\nThus a wave length ( Lambda) corresponds to 2pi radian\n\nAny orbitrary length l corresponds to( 2 pi/ lambda ) x l\n\nThe path differnce l is equivalent to a phase difference of  ( 2 pi/ lambda ) x l\n\nA phase difference of Theta corresponds to a path difference of  ( Lambda/2pi ) x theta.

No it can't.\n\nLaser light goes at exactly the speed of light.

Electromagnetic waves.  That includes x, gamma, visible light etc...\n\nGravitational waves.

Light travels faster than sound.

put simply its complete bullshit... lol, solidification is just the slowing of atoms/molecules, sonce light ALWAYS (dont even go tehre with the whole medium thing, its always) travels at teh same speed... like i said before solidified light is bs. :-)

According to reletivity, the transformed velocity is zero.\n\nPhotons will see each other at rest,\n\nAlso it is interesting to know that it takes no time for photones to travel all the world if ask them.

It seems you are having some misconception about light waves.\n\nLight is energy transformation and it is not matter.\n\nConsider a ray of light. You will draw a line alone and not a wave. \n\nNow consider a point on the line.  The light intensity at this point changes periodically; starting from zero, increases to a maximum, decreases to zero again increases and again to zero. This is repeated periodically.\n\nReading the above lines many come to a conclusion that at this point some thing increases in SIZE; like a wave in water. Once again remember this is energy and is not matter.  Wave like pattern is only an analogy and nothing is displaced at the point. EVERY THING HAPPENS AT THE SINGLE POINT ALONE.\n\nIf we draw a graph, the  locus of all points will look like a wave and  this is what we say light travels in the form of wave and there is  no physical form of wave. \n\nLight possesses wave like properties and light itself is not a wave.

If the deflection surface has any diffraction or diffusion to it, the light may just be redirected imperfectly. 12kV? Jumpin Gigawatts!

Frequency = velocity of propagation / wavelength.\n\nFor light, we assume it is moving in a vacuum, so vp is 3e8 m/s.  The wavelength of 310nm is 310e-9 meters.  Then we plug the numbers in, and we get (3e8 m/s) / (310e-9 m) = 967.742e12 Hz because 1/s is the same as cycles/sec, which is a Hertz.

The property of light is that it takes the shortest route possible between 2 pts. IT IS A WRONG IDEA THAT THIS PATH IS A STR LINE. A str line is the shortest dist in Eucidean Goem, the geom of the Universe is NOT EUCLIDEAN IN NATURE. As for your other ideas, I pt out that a photon never stops travelling unless it gives up its energy. DO NOT USE NEWTON'S LAWS ON THE PROPAGATION OF LIGHT. THE PROPAGATION OF LIGHT IS EXPLAINED BY 2 THEORIES-\nMAXWELLS THEORY OF ELECTROMAGNETISM, speaking of the WAVE ASPECTS\nEISTEIN'S GENERAL THEORY OF RELATIVITY, speaking of the particle nature. GO through these when you r of the proper age to do so, let me warn you that studying the true nature of light requires a huge pre-knowledge of physics and it is very difficult and controversial.

I know that different colors are "visible" at different wavelengths.  So, depending on an increase/decrease in energy, you would be at varying wavelengths?

No, as da 1st prism 'll split it into da spectrum (VIBGYOR) & da 2nd 'll just refract da spectrum & not convert it again into white light.
