FAQs on Electromagnetic Waves Class 12 Notes: CBSE Physics Chapter 8
1. What factors influence the features of electromagnetic waves in Physics Class 12?
As per the Ch 8 Physics Class 12 notes, the electric field and the magnetic field influence the features of an electromagnetic wave.
2. What is the electromagnetic spectrum in class 12 Electromagnetic Waves notes?
If you refer to the Chapter 8 Physics Class 12 notes, the electromagnetic spectrum is the classification of electromagnetic waves as per their wavelength or frequency.
3. What are electromagnetic waves Class 12?
Electromagnetic waves are the waves produced by an electric charge where a magnetic field occurs due to an electric field and vice versa. The waves travel in a direction perpendicular to the magnetic and electric fields. Students of Class 12 will learn about the concept of electromagnetic waves in Chapter 8 Physics. They can refer to the CBSE Class 12 Physics Notes for Chapter 8 available at Vedantu for understanding the meaning and concept of electromagnetic waves.
4. How are electromagnetic waves produced explain Class 12?
Electromagnetic waves are produced by moving electric charges. An electric charge can oscillate with frequency to produce electromagnetic waves. The main source of electromagnetic waves is an electric dipole. In electromagnetic waves, electric and magnetic fields are perpendicular to each other thus making electromagnetic waves transverse. All concepts related to electromagnetic waves are available at Vedantu.

7. What are infrared rays and how are they useful in electromagnetic waves notes class 12 PDF?
Infrared rays are the rays produced by hot objects. The band of infrared rays lies next to the low frequency or long wavelength of the light spectrum. The other name for infrared rays is heat waves because they are hot and produced by hot molecules. Infrared rays are useful in many ways. They are useful for taking photographs at night. They are also useful to study secret writing. They are also useful for giving physical therapy to patients.
8. How do Maxwell's equations relate to electromagnetic waves Class 12 Notes?
In Class 12 Physics Chapter 8, Maxwell's equations describe how electric and magnetic fields interact and propagate as waves. These equations show that changing electric fields create magnetic fields and vice versa, which allows electromagnetic waves to travel through space.
9. What are the properties of electromagnetic waves in ch 8 physics class 12 notes?
Electromagnetic waves have several key properties, including wavelength, frequency, speed, and amplitude. In Chapter 8, you’ll explore how these properties affect the behaviour of waves and their interactions with materials.
10. Why are electromagnetic waves important in Ch 8 Physics Class 12 Notes?
Electromagnetic waves are crucial because they are used in many technologies and communication systems, such as radio, television, and the Internet. Understanding them helps us in various scientific and practical applications.
11. What is the electromagnetic spectrum in electromagnetic waves notes PDF?
The electromagnetic spectrum is the range of all types of electromagnetic radiation. In Chapter 8, you’ll learn about different parts of the spectrum, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, each with different wavelengths and uses.
