Chapter 10: Geometrical Optics | Physics XI First Year Sindh Board

Physics is the study of nature, properties of matter, energy and its inter-conversion from one form to another. The subject of physics is considered as a poster child of mathematics because its roots have emerged from the field of Mathematics.


This is the tenth Chapter of XI PHYSICS titled ‘Geometrical Optics’. In the beginning of this Chapter we will study about the Lenses, Types of Lenses, Power of Lenses, Lens Aberration and Magnification. Then we will move towards the Applications of Lens like Compound Microscope, Telescope, Galilean Telescope and terrestrial Telescope. We will also solve Examples and Problem (Numericals) to enhance our understanding about these topics.

These concepts will be easier for you in accordance with the below mentioned features:

  • Coverage of all the topics in detail.
  • Providing topic wise assessments to Students for real time evaluation and assignments for practicing the questions.
  • Topic wise Past Papers to demonstrate the importance of each topic.
