This presentation explores the fascinating interaction between polarized light and optically active materials, using a sugar solution as the medium. When linearly polarized white light passes through such a solution, the sugar molecules rotate the plane of polarisation due to their chiral nature. This results in a visually stunning rainbow, as different wavelengths (colours) are rotated by different amounts. We will examine the physics of light propagation, polarization, and the molecular interactions responsible for optical activity. Additionally, we will explore the wavelength dependence of dispersion and how polarization relates to dipole radiation. The presentation will conclude by highlighting how these interactions connect fundamental principles of electromagnetism and molecular structure, offering a deeper understanding of the observed phenomenon.
