Summary of HC Verma Solutions Part 2 Chapter 40: Electromagnetic Waves
FAQs on HC Verma Solutions Class 12 Chapter 40 - Electromagnetic Waves
1. 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. The students can also refer to the CBSE Class 12 Physics Notes for Chapter 8 available at the Vedantu website for understanding the meaning and concept of electromagnetic waves.
2. 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.

5. What are infrared rays and how are they useful?
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. To know more about the topic, click here.
