Question

plane of polarized light is effected by
1.identical molecules
2.chiral molecules
3.biological molecules
4.all of these​

Answer 1

Answer:

I think the answer is 2.chiral molecules.

Answer 2

Option.2 is the correct answer which is chiral molecules

A plane of polarized light is affected by chiral molecules

Explanation:

• The plane of polarized light is rotated by Chiral molecules.
• Just like chiral molecules in the same way a quartz plate also can rotate the plane of polarized light.
• It can change the speed of light in two different ways.
• The polarized light goes slower in matter in comparision to that of vacuum.
• Here the slowdown of light in matter is determined by refractive index n.
• The large value of n will make the light go slower and keep the light longer in the matter.
• If the matter present is chiral, it will give the light in two different speeds, then one for the light will rotate its polarization clockwise and the other counter-clockwise.
• If the polarized light has two parts that is clockwise and counter-clockwise. Then the two parts are combined and thus the light will show a direction of polarization.
• When these two parts of the light pass through the chiral matter, one will go faster and the other one will be slower. It will result  that the polarization of light is rotated from its normal way.
