Description:
This didactic activity is based on computer based learning through sensors and advanced tools for data acquisition and analysis. The fundamental studies related to polarization namely Malus’ Law and study of elliptical and circular polarization have been automated using rotary motion and light sensor. This computer based laboratory allows a student to online collect, analyze and display the data during experimentation leading to better understanding of otherwise a very difficult concept of polarization. Also, time required for carrying out the study of elliptical and circular polarization is substantially reduced from 3 hours to less than half an hour.
