In electromagnetic waves electric and magnetic fields oscillate in mutually perpendiculor directions as well as perpendicular to the direction of propagation if e.m. wave. Class 12 Physics Chapter 8 Electromagnetic Waves Session 2024-2025.
Frequency of electromagnetic waves = Frequency of oscillating charge = v. Class 12 Physics Chapter 8 Electromagnetic Waves Session 2024-2025.
Electromagnetic Waves are coupled time-varying electric and magnetic fields propagating in space with the speed of light. Class 12 Physics Chapter 8 Electromagnetic Waves Session 2024-2025.
Large-scale transmission of electric energy over long distances is achieved using transformers. Step-up transformers at power plants increase voltage, reducing current to minimize transmission losses. High-voltage electricity travels through transmission lines efficiently. At distribution points, step-down transformers lower the voltage ...
