NCERT Grade 12 Physics Chapter 10, Wave Optics. This is a part of Unit 6, Optics. One of the most important Units of NCERT Grade 12 Physics; Optics holds a total weightage of 14 marks in the final examination. In this chapter students will first learn the original formulation of the Huygens principle and derive the laws of reflection and refraction. In further sections of the chapter they will learn about the phenomenon of interference which is based on the principle of superposition, the phenomenon of diffraction which is based on HuygensFresnel principle. Eventually, towards the conclusion of the chapter; the phenomenon of polarisation which is based on the fact that the light waves are transverse electromagnetic waves shall be learnt.
Introduction to Wave Optics, Huygens Principle, Refraction and Reflection of Plane Waves Using Huygens Principle, Refraction of a plane wave, Refraction at a rarer medium, Reflection of a plane wave by a plane surface, The doppler effect, Coherent and Incoherent Addition of Waves, Interference of Light Waves and Young’s Experiment, Diffraction, The single slit, Seeing the single slit diffraction pattern, Resolving power of optical instruments, The validity of ray optics, Introduction to Polarisation, Polarisation by scattering and Polarisation by reflection are the topics learnt in this chapter.
Ray diagrams, graphs, illustrations and examples associated to daily life make this chapter very interesting and easy to learn. Solved numeral problems and unsolved ones for practice make the students understand the concept better and develop a strong grip on the subject. The contribution of eminent scientists such as Huygen, Thomas Young and others in the field of Wave Optics has helped to develop laws on the topic that the students shall study through this chapter. Detailed derivations to help derive formulas and equations will aid to solve the problems and understand the concepts.
