Summary of HC Verma Solutions Part 1 Chapter 18: Geometrical Optics
FAQs on HC Verma Solutions Class 11 Chapter 18 - Geometrical Optics
1. What is the difference between geometrical optics and physical optics?
Geometric optics is all about refraction and reflection of light whereas physical optics deals with the topics like interference, diffraction, polarization, etc. Physical optics is viewed through wave theory of light and geometric optics are viewed through the aspects of physical nature of light.
2. What are the limitations of geometrical optics?
Geometrical optics is very simple and based on the nature of light. It excludes the phenomenons like diffraction, interference, or any phenomenon which are related to light.
3. Why HC Verma's solutions are important for exam preparation?
HC Verma's solutions are important because HC Verma consists of conceptual questions and problems on important topics like focal length, magnification, image-object distance, celestial bodies, real-apparent depth, refractive index, critical angle, lateral displacement, etc.
4. How does Vedantu’s solution to the problems of HC Verma help in the preparation?
Vedantu takes the initiative to solve the complex problem of HC Verma in a simple and lucid way to make the conceptual grip of the chapter stronger. Solutions are broken down into simple steps maintaining the approved standard of CBSE. Solving solutions from HC Verma also helps in the preparation for the competitive exams and therefore, Vedantu pays extra attention to the accuracy of the solutions.
5. According to HC Verma Class 11 Physics Part-1 Solutions for Chapter 18, who invented Geometric Optics?
The geometer Euclid (c. 325 BC–265 BC) was the first known author of a geometrical optics treatise. Euclid began his study of optics with a set of self-evident axioms, just as he did his study of geometry. Euclid did not define the physical nature of these visual rays, but he did discuss the effects of perspective and the rounding of things seen at a distance using geometric principles. Whereas Euclid's analysis was limited to simple direct vision, Hero of Alexandria (c. AD 10–70) extended geometrical optics principles to include reflection problems.
6. Why is Geometrical Optics important for the class 11 Physics exam?
Geometrical optics is the fundamental tool used in the design of almost any optical system, image forming or not. We utilize the natural ideas of a light beam, which is generally characterized as the way along which light energy travels, just as surfaces that mirror or communicate light. Geometrical optics methods allow us to learn about the conditions that govern the formation of an optical image of an object as the sum of the images of the object's points.
7. According to HC Verma Class 11 Physics Part-1 Solutions for Chapter 18, how are Optics used in everyday life?
Optics is the foundation of optical instruments. Mirrors and lenses are used to reflect and refract light, as well as to create images. Convex lenses and mirrors are used in light microscopes and telescopes to magnify images of very small or distant objects. A convex lens is used in a camera to create a reduced image of an object. Understanding light's behaviour was critical for the development of optical instruments such as microscopes, telescopes, and cameras, as well as optical fibers.
8. Following the concepts taught in Class 11 Physics for chapter 18, what is the difference between Physical Optics and Geometrical Optics?
Physical optics is mainly bothered with the nature and properties of light. It is the branch of optics concerned with interference, diffraction, polarization, and other phenomena for which the geometric optics ray approximation is inapplicable. Geometrical optics is bothered with the principles that control the image-forming properties of lenses, mirrors, and other light-based devices. The primary distinction between physical and geometric optics is that light in physical optics is regarded as an electromagnetic wave, whereas light in geometrical optics is regarded as travelling in straight lines.
9. How does Vedantu help in preparation for the class 11 exam of Physics?
Vedantu assists in simplifying complex problems in order to strengthen the conceptual grasp of the chapter. To make things easier and less complicated, solutions are broken down into smaller steps. We require a mentor to assist us in solving complex problems, and Vedantu makes this possible by offering online home tuitions. Vedantu not only simplifies the problem, but it also adheres to CBSE, ICSE, and other boards' standards. It retains the flexibility needed to help students better understand problems.
