Question

wwhat do u mean by optical activity show how fresenl's theory explains the optical rotation?​

Answer 1

Explanation:

It means that plane of vibration of the plane polarized light changes (rotate) when it passes through any substances. This property of rotating the plane of vibration by a substance is known as "Optical Activity please mark it as brainliest.

Answer 2

Answer:

Optical activity is a property unique to chiral substances.Optical rotation is the extent (measured in degrees) to which a solution of a molecule will rotate plane-polarized light, as measured by a polarimeter. Optical rotation is dependent on concentration, path length, temperature, and the wavelength of light used, as well as the solvent.

In accordance to Fresnel's theory, When a Polarizer and an analyzer are crossed, no light comes out of the analyzer. ... It means that plane of vibration of the plane polarized light changes (rotate) when it passes through any substance. When a plane poiarised light is passed through certain substance, the plane of polarisation of the emergent light get rotated through certain angle about the direction of propagation of light..
