Class 12 Physics NCERT Electromagnetic Waves
The chapter Electromagnetic Waves from Class 12 NCERT Physics explains the nature, properties, and applications of electromagnetic radiation. Students learn how changing electric and magnetic fields generate electromagnetic waves, as described by Maxwell’s equations. The chapter covers the characteristics of electromagnetic waves, their speed in free space, and their transverse nature. It also introduces the electromagnetic spectrum, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each region of the spectrum is discussed along with its applications in communication, medicine, and technology.
NCERT Class 12 Physics provides clear explanations, diagrams, and examples to strengthen conceptual understanding. Electromagnetic Waves is important for Class 12 board exams and also plays a key role in competitive exams like JEE and NEET. By mastering this chapter, students gain insight into the unification of electric and magnetic fields and their significance in modern scientific and technological advancements.
