Chapter 8: Electromagnetic Waves
NCERT Class 12 Physics, Part I, Chapter 8. 3 lessons, 7 narrated 3D videos, 3 simulations and 6 quiz questions, following the textbook section by section.
- Displacement currentFaraday showed that a changing magnetic field produces an electric field. Maxwell asked the reverse question: can a changing electric field produce a magnetic field? The…
- Electromagnetic wavesA charge at rest has only an electric field around it. A charge moving at a steady speed is a steady current, and it makes a steady magnetic field. Neither of these…
- The electromagnetic spectrumA radio signal, the heat from a stove, sunlight and a hospital X-ray look nothing alike. Yet all of them are electromagnetic waves: oscillating E and B fields that cross…
