What Is Optically Active Material? A material that (a) rotates the polarization of light that passes through it, (b) exhibits different refractive indices for left-hand and right-hand circular polarizations, and (c) demonstrates birefringence. What are optically active substances? Optically active: A substance which has optical activity, i.e., a substance which rotates the plane of plane

What Is The Importance Of Polarization?

by

What Is The Importance Of Polarization? Polarization, however, is an important property of light that affects even those optical systems that do not explicitly measure it. The polarization of light affects the focus of laser beams, influences the cut-off wavelengths of filters, and can be important to prevent unwanted back reflections. How is polarization used
