When you are studying for the CBSE Class 12 Physics Examination, it is important to make sure that you have access to the proper notes. These class 12 physics notes can make all the difference in your success. They will help you to get a clear idea of the subject matter as well as provide you with a better understanding of how to tackle the exam.
Magnetism and matter
Magnetism and matter is an important topic for CBSE class 12 students. It covers a wide range of topics. There are various notes available on the internet to help you with your revision. If you’re looking for a convenient way to study, you can also download the notes from myCBSEguide. These class 12 chemistry notes are very useful as they cover all the relevant topics and provide a solution to every question.
NCERT Class 12 Physics chapter 5 includes the discussion of Magnetism and Matter. The notes discuss how the force produced by a magnet attracts or repels another object. In addition, it discusses the properties of different materials. This chapter is essential for students preparing for their exams.
The magnitude of the Earth’s magnetic field is about 10-5 T. Interestingly, this field has been present on the Earth since its formation. But the strength of its field changes from place to place.
Electromagnetic waves
Electromagnetic Waves (EM Waves) are waves that carry momentum and energy. They are used for communication, and have many medical applications.
The main source of electromagnetic waves is an electric dipole. In order to generate electromagnetic waves, the dipole needs to be accelerated. This is done by a change in the electric field of a wire or an antenna. A wave can be propagated through any medium. However, the speed of the waves changes as the charges in the wire move.
The frequency of an electromagnetic wave ranges from 500 kHz to about 1000 MHz. These waves are used for radio transmission and television signals. They are also important for aircraft navigation.
It is possible to make EM Waves go faster by applying the Ampere’s Circuit Law. This law defines the relationship between the electric and magnetic fields.
Wave optics
If you want to prepare for the CBSE Class 12 exam, you need to get hold of a few good revision notes. Whether you are looking for a few chapter-wise notes or revision tips and tricks, these notes will help you get through the exams with ease.
One of the most important chapters in Grade 12 Physics is Wave Optics. In this section, you will learn about the various optical phenomena like diffraction, reflection, refraction and interference. You will also find out how to apply Huygen’s code to reflect light.
The law of refraction is one of the most interesting things to learn about in this chapter. This law describes the way light refracts at a plane and a cylindrical interface.
Another important aspect to know about is the wavefront. A wavefront is the locus of all wave points in a medium, which are all vibrating in the same frequency.
Self-assessment
A well-developed study plan is important for any student preparing for an exam. This includes an accurate study schedule, a clear set of objectives and a focus on each topic. For example, students should try to solve as many of the questions in the NCERT Class 12 Physics textbook as possible. Using sample papers and revision notes is also helpful.
Students should also keep in mind that physics has a very vast syllabus. To prepare for the exam, students must work hard. They should make a point to spend at least one hour a day studying. In addition, they should take note of the weightage of each unit of the syllabus.
It is essential to develop a plan of attack to score good marks in the exam. During the last three months before the exam, students should concentrate on completing the tasks assigned to them. If they have been able to complete these tasks, they can feel more confident in the exam hall.
Preparing for the exam
In the upcoming Board exams for Class 12th, students have to prepare well to secure good scores. For preparing for the board exams, you need to start early. To get a clear idea of the type of questions you will be asked in the exam, you need to solve a large number of practice papers.
The CBSE Physics paper is designed to test your knowledge of Physics. It consists of numerical questions as well as derivations. Hence, you must study the topics thoroughly and answer the questions in the shortest time possible.
To make the most of your time, you need to make an outline. This will ensure that you do not overwrite your notes. You should also practice solving numerical problems.
