Students can search for important questions for class 12 physics online. They can find different websites that offer important questions for class 12 physics. They can download the PDF file for important questions and can practice them when needed. Students should find chapter-wise important questions for class 12 physics. In school, teachers may not be able to answer all the important questions due to lack of time. Downloading chapter-wise important questions for class 12 physics will help students to practice all-important questions and score high marks in the board exams.
Students can read this article to know the important topics for each chapter in class 12 physics:
It is the first chapter and in this chapter, students will learn about the concepts of light and laws of refraction and reflection. Students should understand the laws and the concept of light in this chapter. In this chapter, students will also study different principles such as the Huygens principle. They will also study wave theory. Students should focus on all important questions based on the principle of superposition and wave theory in the chapter.
In this chapter, students will study different electronic devices in detail. They should understand the functioning of semiconductors and conductors. It is a vast chapter; therefore students may have to spend more time on this chapter.
In this chapter, students learn how a communication system works. They have to understand the different channels through which the communication system works. The communication system could be with wires or without wires. Thus, students need to understand the difference between the two. They also have to understand the working of a transmitter.
Atoms and nuclei
In this chapter, students should focus on the different models of atoms proposed by different scientists. They should understand the difference between the different models of atoms. They also have to study the different elements of an atom. Students will also learn about the nucleus in detail. Thus, students should read all important topics in detail to understand the basic concepts of this chapter.
In this chapter, students will study the concept of electrostatic force. They will also study charges, electric field, capacitor, torque, etc. It is an important chapter from the exam point of view. Students should understand the concepts in this chapter to score high marks in their class 12 physics exam.
Dual nature of matter
This chapter deals with the photoelectric effect. Students will study the concept of photo electricity in this chapter. They will study the conversion of one form of energy to another. They will also study the law of conservation of energy. Students will also study about special features of different processes. It is a theoretical chapter and is easy to understand.
It is a lengthy chapter and is important. Students get short and long questions from this chapter. They will study electrostatic field lines and their behavior. They will also study the laws of electricity and magnetism. Students will also study the different forces exerted on electrons, protons, neutrons, and wires in the electric field.
What is the importance of studying important questions for class 12 physics?
Students can study important questions for class 12 physics for scoring high marks in their exams. Important questions are selected based on the previous year’s question papers. Students can get an idea about the type of questions that are asked in the exams.
Students can know the important topics and can focus more on the important topics for scoring high marks. For example, a semiconductor is an important chapter and carries 8 marks. Therefore, students should focus on this chapter to score high marks.
Optics is a difficult chapter and it carries 14 marks. Therefore, students need to spend more time on this chapter to understand the basic concepts. Important questions can help students to save time as they can select important topics from the chapter and can focus more on the important topics.
Electrostatics is a lengthy chapter and consumes too much time. Students can only focus on the important questions of this chapter rather than studying the whole chapter. Similarly, magnetism is also a lengthy chapter and students can study important questions to understand the concepts of this chapter.
Students should also focus on EMI which is also an important chapter from the exam point of view. It is important for both board and competitive exams.
Students can get information about short questions and one-mark questions from the important questions given online. This can help students to prepare for their competitive exams as well. Students should solve all types of important questions to score high marks in their exams.
Students should understand the concepts of physics to score high marks. They should search for the important questions on the internet to get high marks. Important questions can help students to get an idea about the type of questions asked in the board exams. Important questions can help the students of class 12 to form a strong base in physics.
