Polarization Class 12 Physics

Polarization falls under waves and optics portion of class 12 physics. Polarization Class 12 Physics Notes is designed according to the updated syllabus of 2080 and it covers all the important portion of the chapter. Students can easily prepare their notes, study for test or exams by taking the help of class 12 polarization Notes.

  Chapter – 13  
Polarization 

Polarization is a property applying to transverse waves that specify the geometrical orientation of the oscillations. Light is an electromagnetic wave in which electric and magnetic field vectors are sinusoidally perpendicular to each other as well as they are perpendicular to the direction of propagation of light waves.

  Chapter Overview  
In this chapter we are going to learn the following concepts, ideas or topics;

  1. Experimental Demonstration of Polarization
  2. Experimental Verification of Transverse Nature of Light
  3. Polarization by Reflection: Brewster’s Law
  4. Unpolarized and Plane Polarized Light

Now let’s move on to the notes of polarization. The PDF given below contains all the notes which includes all the topics mentioned in the chapter overview. We request students to use the notes of polarization wisely for the purpose of making notes and preparing for the board examination. 

You have to scroll down the PDF to view all the notes of polarization. This PDF contains 14 slides in total which contains all the required notes of polarization. It doesn’t contains the numerical problems so if you are searching for the numericals then you’ll find them in the next PDF given below. 

Polarization by Selective Absorption: Malus’s Law

The most common for technique producing polarized light is to use a material that transmits waves whose electric fields vibrate in a plane parallel to a certain direction and that absorbs waves whose electric fields vibrate in all other directions.

Polarization Class 12 Physics Numerical Questions 

Those students who want to practice the numericals from polarization chapter can practice the questions given in the PDF below. We have solved the selected numericals which will provide you the method of solving the numericals. 

This PDF contains all the important numericals from polarization chapter. In addition to the numericals it also contains all the required formulas used for solving the numerical problems of this chapter. 

If you are willing to practise more numerical problems for your examination then you can practice the questions listed below. 

  • A parallel beam of unpolarized light in air is incident at an angle of 55º on a plane glass surface. If the reflected beam is completely plane polarized, find the refractive index of the glass and the angle of refraction of the transmitted beam. [Ans: 1.428, 3.5]
  • Calculate the polarizing angle for the light travelling from water of refractive index 1.33 to glass of refractive index 1.53. [Ans: 49]
  • The critical angle for light in a certain substance is 45°. What is the polarizing angle? [Ans: 54.7°]
  • A beam of light is incident at polarizing angle on a piece of transparent material of refractive index 1.62. What is the angle of refraction for the transmitted beam? [Ans: 31.7°]
  • The polarizing angle for a medium is 60°. Calculate the velocity of light in the medium. [Ans: 1.73×108 m/s]

These questions are provided for practising purposes. So we haven’t provided the solutions of the numerical problems. However, if you are facing problems while solving these numericals then we request you to copy the questions and paste it in Google to get the solutions of that numericals. If that doesn’t work then you can contact us through our telegram channel to get the solutions.
