Download [PDF] Geometrical Optics - Kota Study Material for IIT-JEE



The chapter ''Geometrical Optics'' or "Ray Optics" is a significant portion of the physics syllabus of JEE Mains & Advanced and other engineering entrance exams. Moreover, it also forms a major part of the physics syllabus of intermediate exams conducted by various boards in India. In order to have a proper and conceptual understanding of the subject, the very first requisite is to follow quality study materials. As far as your board exams' preparations are concerned, only the standard NCERT texts books are enough and reliable, however if you are preparing for competitive engineering entrances, you must follow some additional books and study materials as well which strictly follow the syllabus of those entrances.

This page contains the PDF download link of the chapter ''Ray Optics" (also called as geometrical optics) followed by the premier JEE coaching institutes of Kota. The module consists of brief and to the point theory discussion, good number of solved illustrations and then a set of unsolved problems of various types for your practice and also includes previous years asked problems in JEE Mains and Advanced.

Ray Optics is one of the two core branches of Optics (the other being wave optics). It is the subject which deals with the behavior of light and the corresponding optical events taking place when the size of structures with which the light interacts is too large as compared to the wavelength of the incident light wave. In such cases, the ray approximation of geometrical optics holds quite good. Light is approximated as moving along straight line path in homogeneous medium. However, whenever a light beam meets an interface separating two different media (having different indices of refraction), it may deviate from its original straight line path. In such cases, two types of optical events occur simultaneously at the interface  ̶̶  Reflection and Refraction of light. If there is an optical medium with continuously varying refractive index, the light ray may follow even a curved path due to continuous refraction and reflections taking place.

Ray Optics does not account for certain optical events such as interferences and diffraction. These optical phenomena occur significantly when the size of obstacles which a light ray encounters becomes comparable to the wavelength of the light wave. In these cases the wave nature of light comes into picture (Wave Optics).
