Students generally complain that they are unable to understand the mindset or marking pattern followed by the examiner in board examination. Our solution book covers all the 15 chapters in the most clear and well refined way. We have used very easy and interactive language so that students will feel as if they are being taught by a teacher itself. After studying the solutions you will not need any additional help, that’s our promise.
If any problems can be solved in multiple ways, we have even provided that. All the back exercise questions from NCERT physics class 12 PDF book are solved following the latest pattern followed by Central board of secondary education. Along with that we have solved the previous year’s question papers also which will help in better understanding of examination pattern.
The chapters such as electromagnetic, waves and induction are quite difficult to understand. Wave and ray optics which are the most confusing chapters, have been explained with proper illustrations and expiation. We have made every possible effort to make the solutions become easier for students to digest, make sense and can be grasped easily.
Our lives are nonexistent without the concept of physics. Be it geology, biology, chemistry etc everything is based on the application and concepts of physics. In medical science we use X-Rays, Ultrasounds, radiology and all the equipment’s are the blessings of physics. The communication, digitization and the travelling are interrelated with physics.
