As part of the course curriculum of Physics of class XII, students do a comprehensive theoretical study about the wave nature of light specially related to interference, diffraction and polarisation. But, these studies are not backed up by any experiments. This makes the understanding of these complex topics very difficult. The purpose of the present outreach activity is to make students do many hands-on experiments on the above topics. The experiments have been designed keeping in mind the various theoretical concepts taught to the students. The studies are helpful in making the students understand fringe formation, intensity variation across the fringes formed helping them compare interference and diffraction fringes, dependence of fringe separation on various parameters, linear polarization, Malus‟ law and Brewster‟s law. The tools used to perform the experiments include He-Ne/ diode laser(s), Laptop/Digital Storage Oscilloscope, CCD, various optical components like set of polarisers and analysers, glass plate and hardware components like single slit and double slit. The class XII students are divided into batches and each batch is handled by a team of three University of Delhi at ANDC SPIE student chapter members. The gains of the activity are measured through pre and post-tests.
