Optical storage is the storage of data on an optically readable medium. The optical rotation is proportional to the concentration of the optically active substances in solution. Particles within the optically thin clouds cause colored interference fringes by diffraction. Anomalous diffraction theory applies to optically soft but larger particles. Recombination and generation are always happening in semiconductors, both optically and thermally. The plane of polarization is turned by optically active compounds. It is exhibited in the absorption bands of optically active chiral molecules. Many electrophiles are chiral and optically stable. This is consistent with the behavior of a geometrically thick but simultaneously optically thin ring. Materials that allow the transmission of light waves through them are called optically transparent. The operator tracks the target using the aiming unit's optically stabilized sight. Nanocellulose can be used to prepare flexible and optically transparent paper. The latter design provides more optically reflective properties. An existing hologram can be copied by embossing or optically. In general, this phenomenon will be exhibited in absorption bands of any optically active molecule.
