You will understand it better if you read Principle of least action. Moreover, refraction of light also depends upon the geometry and internal atomic structure of that particular element. Here's Fermat's Principle or Principle of Least Action http://en.wikipedia.org/wiki/Fermat's_principle...

See, the phase constant can be anything, any angle. So, it is not necessary to add pi/2 always. If you subtract pi/2 in the above equation, you still get the same answer but with opposite sign indicating that the motion is along the -ve side of the cartesian co-ordinate system.

Hello, KiNGGeexD here's the solution for your probem. The Sin and the Cosine functions depends upon the position of the object with respect to the observer. When you look at the derivation of the displacement equation, you get the equation to be x = A sin (wt) or more specifically x = A...

So, what if i was there in the medium? Which means if i was in the glass slab, can I see colour change? Devendra S. Chavan

I searched for the images of refraction on google images and i saw an image where a laser light was incident on a regular glass slab. Bending of light was clearly seen in the picture. According to Snell's law the refractive index of any particular medium is the ratio of angle of incidence to...
