As Physics exams are near so let's revise the total concepts of Wave Optics and related important formulas. This lecture will be a fun and I'm sure you'll fall in love with Physics. We'll try to clear our doubts and various exam important topics so that all your doubts will be cleared and you'll be able to achieve good marks related to this topic. We'll discuss various topics named Huygens Principle its applications, Important Topics related to wave optics, Optical Phenomena related to wave optics such as interference, diffraction, YDSE, Single Slit diffraction and all the related syllabus based topics. We'll also have an interactive session in which I would try to solve your queries and doubts related to the topic. I promise if this would be a successful operation then we'll have an another lecture where we'll have a quick revision of Physics and Mathematics for Class-12 Term-2 Examinations.
