Interference falls under waves and optics portion of class 12 physics. Interference 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 interference Notes.
Chapter – 11
Interference
Two sources are said to be coherent if they emit continuous light waves of the same frequency or wavelength, same amplitude and if they are always in phase with each other or have a constant phase difference. To observe the interference phenomena of light, sources must be coherent of light. In practice, two independent sources are not coherent.
Chapter Overview
In this chapter we are going to learn the following concepts, ideas or topics;
Now let’s move on to the notes of interference. 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 interference 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 Interference. This PDF contains 8 slides in total which contains all the required notes of interference. 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.
Interference of Light
When two identical waves coming from coherent sources overlap at a point in space, the combined wave intensity at that point can be less or greater than the intensity of either of the be waves. We termed this effect as interference. Thus, interference of light is the phenomenon of non-un distribution of light energy in a medium due to superposition of light waves from two coherent sources.The interference can either be constructive when the net intensity is greater than the individual intensities, or be destructive, when the net intensity is less than the individual intensities
Interference Class 12 Physics Numerical Questions
Those students who want to practice the numericals from interference 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 interference 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.
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.
