Optical activity happens in a solution with components of quartz, sugar or certain gases. It is when the plane of linearly polarized light is turns to the direction of movement through the components.
Yes, water can exhibit optical activity if impurities or dissolved substances are present. Pure water itself is not optically active, but impurities such as dissolved minerals, gases, or organic compounds can cause it to rotate the plane of polarized light.
The necessary condition for a molecule to exhibit optical activity is for it to be chiral, meaning it cannot have a plane of symmetry. This asymmetry causes the molecule to interact differently with polarized light, rotating the plane of polarization as it passes through.
Both are optically inactive, but for different reasons. A racemic mixture contains chiral molecules that, individually, are optically active. But the mixture contains optically active enantiomers, which essentially cancel out each other's optical activity (one enantiomer rotates light one way, the other rotates it back). A meso compound, however, is optically inactive on its own. It can have chiral centers within its structure, but due to symmetry it will still be optically inactive.
Racemic mixture of tartaric acid consists of equal amounts of its D- and L-enantiomers, resulting in a 1:1 ratio. This forms a structure that lacks optical activity because the optical rotations of the enantiomers cancel each other out.
Optical activity in a substance depends on its symmetry and chirality. Chiral molecules exhibit optical activity, where they rotate the plane of polarized light. The state of the substance, such as solid, liquid, or gas, does not significantly affect its optical activity as long as the molecular structure and chirality remain the same.
Some isomers lack optical activity because they have a plane of symmetry or a center of symmetry that results in the molecule being superimposable on its mirror image. This makes them achiral and unable to rotate the plane of polarized light, thus lacking optical activity.
Optical activity depends on factors such as the presence of chiral molecules, the specific arrangement of atoms in the molecule, and the interaction of polarized light with the molecule's asymmetric structure. The extent of optical activity is also influenced by the concentration of the chiral molecule in solution and the path length of the light passing through the sample. Ultimately, these factors determine the magnitude and direction of optical rotation exhibited by a substance.

What a charming question! But since the rainbow has no physical presence, it contains nothing. It is just an optical effect. Another optical effect could be that of a shadow, which really has no presence or activity.
Optical inversion refers to a phenomenon where a chiral molecule rotates plane-polarized light in the opposite direction from its enantiomer. This occurs due to the molecular structure causing different interactions with polarized light. It is a key concept in understanding the behavior of chiral compounds in optical activity.
