How differently light behaves? In the eyes of modern and classical physical studies.

Do you know the special properties of light? In ancient days the speed and its properties are observed on the basis of physical existence…and more clearly I can say by observing the nature of light that what we see from our eyes.
newton is one of them who started to observe the light from eyes differently..what a joke all we see from our eyes only..then what different Newton had seen? confused let me explain around 1690 Newton started his studies on the light. he used the special instrument called prism. nowadays prism is common.

But in the 16th century, Newton used it as one of great science device, to reveal the secrets of light. he saw not only light, but the color full light emerging from the prism.(VIBGYOR)this is what I history mankind newton is the first person to observe, such a phenomenon. for today it’s a simple thing. and started to give his conclusions.he briefly started to study optics. and written his book ‘Optics’.
but let me give some properties which cannot be explained by just looking through naked eyes.

  • Light can move through a vacuum.
  • Light transports energy.
  • Light has angular momentum: it can rotate bodies.
  • Light has momentum: it can collide the particles.
  • a special property friends my future blog will be on this, light moves with other light undisturbedly.
  • Light in outer space moves faster than all objects in this universe.
  • The speed of light, its true signal speed, is the forerunner speed. 
  • 299 792 458m/s is the speed of light in vacuum.and 30c.m/n.s(30 centimeters per nanoseconds.1/1000000000.
  • The proper speed of light is infinite.(credit: motion mountain_relativity)
  • Shadows can move without any speed limit.(credit: motion mountain_relativity)
  • Light moves in a straight line when far from matter.
  • The high-intensity light is a wave.(credit: motion mountain_relativity)
  • Light beams are approximations when the wavelength is neglected.
  • In matter, both the forerunner speed and the energy speed of light are lower than in vacuum.
  • In matter, the group velocity of light pulses can be zero, positive, negative or infinite.these are the properties of light which are gifts of quantum physics.or modern physics


The era of quantum physics began in 1905(see my previous post for more information)this changed the world into quantum world.and some property of light is very strange and it was a miracle thing for ancients, hence may be miracle must be revealed as the common thing,so people from 1000s of years started to study and open the well of lightning light information gradually.i hope you understood.thanks for reading.
