Why can't an "upside down" chiral molecule neutralize the polarized light effect? [duplicate]

Steve Mould did a nice video a few months back called "Why Sugar Always Twists Light To The Right" (link is timestamped at the critical part). However his explanation was not complete. He ...

Do isotopic groups cause optical activity?

I understood the simplified reason for optical activity of a compound based on the difference in the angular velocities of counter-rotating circularly polarized light. The difference is due to the ...

Why left and right circularly polarized light have different index of refraction in chiral media?

This is a followup question of (Dependence of the angle of rotation on the wavelength of plane polarized light). Ron's answer tells about the difference between left and right circularly polarized ...

Dependence of the angle of rotation on the wavelength of plane polarized light

Wavelength difference is a big deal, I know. It can solely change the whole interaction between the chiral molecule & the light. But I am not sure what's the mechanism by which light of different ...

Discovery of optical activity of enantiomers - where did the idea of using polarized light came from?

According to Wikipedia, optical activity was first observed in 1811 in quartz. Louis Pasteur's contribution is also mentioned there and in other sources as a major advancement in establishing optical ...
