    What happens if an unpolarized light is sent through a quarter wave plate?and why ?

    • @anoopkrishna20000
      @anoopkrishna20000 4 роки тому +3

      I think quarter wave plate's job is to convert the polarisation state to elliptical and circular. It donot do the work of polariser. So all the linear components of the Unpolarised light get converted to circular/ellipticall ones

      @@anoopkrishna20000 agreed. what would be interesting is to analyze the distribution of all the linear components before and after the waveplate, as they certainly don't get polarized in the same way depending on their angle to the principal axes

      The same thing which happened to a polarized light

    I think particles like photons are in orbit likely with dark matter particles giving them an apparent axial wave or circular helical wave as they travel, depending on the orientation of their orbit. I think light travels thru the 2 polarized filters when a 3rd is introduced at 45 degrees because some particle orbits are deflected into that orientation or circular and pass thru. This would explain the double slit results too.

    Sir... what is the nature of emergent light when circularly polarised light is passed through a quarter plate

    • @amramjose
      @amramjose 6 років тому

      The professor passed away, you can get an answer to your question from multiple photonics sites.

    • @trambakphysik7
      @trambakphysik7 4 роки тому +2

      If you pass circularly polarised light through a QWP, you'll get a linearly polarized light emerging out.

    I appreciate the demonstration.
    The terms "elliptically" polarized, and "circularly" polarized light, are horribly misleading terms for what is happening. They should have used other terms for what is actually happening with the components of the polarized light. It simply refers to the effect of the electric field component of the light either in alternative half waves (elliptical, based on the shape of a half wave), or on each half of the electric field wave equally (which they call circular).
    They should have come up with better terms than this.

    If light was 'particles' they would go through all the polarizing filters.

    Ok. This was a very useless presentation! Thanks nonetheless.
