Acoustic Phenomena falls under waves and optics portion of class 12 physics. Acoustic Phenomena 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 acoustic phenomena Notes.
 Chapter – 9 Â
Acoustic PhenomenaÂ
When a sound wave propagate in air by means of compression (region of maximum pressure) and rarefaction (region of minimum pressure), it can be described either in terms of the longitudinal displacement suffered by the particles of the medium (called displacement wave which we have discussed in chapter 6) or in terms of the excess pressure generated due to compression and rarefaction (called pressure wave).
 Chapter Overview Â
In this chapter we are going to learn the following concepts, ideas or topics;
Now let’s move on to the notes of acoustic phenomena. 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 acoustic phenomena wisely for the purpose of making notes and preparing for the board examination.Â
You have to scroll down the PDF to view all the notes of acoustic phenomena. This PDF contains 19 slides in total which contains all the required notes of acoustic phenomena. 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.Â
