Electromagnetic Waves || for Class 12 in Hindi
In this Physics video in Hindi for Class 12 we explained what electromagnetic wave is and how it is produced. We also explained the formula for electric and magnetic field in that wave. This topic is from Chapter 8 : 'Electromagnetic Waves' for Class 12 from NCERT.
Electromagnetic wave is the oscillation of electric and magnetic fields, which propagates through space and carry energy.
Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. Electromagnetic waves travel at the speed of light, commonly denoted c. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave.
Electromagnetic waves of different frequency are called by different names, viz., radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
James Clerk Maxwell derived a wave form of the electric and magnetic equations, thus uncovering the wave-like nature of electric and magnetic fields and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave.

Sir i can surely say that with your video anyone can easily crack exams like jee because you always focus about the real concept not any question motive concept.
Really sir , you have changed my way of thinking. I love physics because I got a best teacher in physics that's you.
Yeh chapter continue karte raheye sir..... Main ek hi flow apki videos se main ye chapter complete karunga ❤️🥰🤞
You are amazing sir. Respect from Nepal....
Sir please make more videos for bsc 2nd year please sir
Truly addicted with ur channel thank you helpful❤
Thank you sir for your hardwork 🍀
Think you sir for better understanding
Hello sir
Awsome sir, we want more videos like that. I like your accent
Sir, u r great teacher ❤
Thank you sir G🙏🏼
Thankyu sir
The chapter was waiting to be explained beautifully by u sir. Thanks
Thank you sir 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Sir aap vedio recording ke liye kon sa software use krte he...
Thankyou sir
Such a great lecture inducing creativity. Which we rarely get in indian education. Thank you sir you first introduced me to special theory of relativity. Thanks a lot for that.
Thanks
