====================================
Video Description:
📚 Class 12 Physics – Electromagnetic Waves Chapter
In this video, we will solve an important numerical based on the electric field equation of an electromagnetic wave in vacuum:
👉 E = (6.3 N/C)cos[(1.5 rad/m)y + (4.5×10⁸ rad/s)t]

We’ll cover step-by-step:
🔹 Direction of propagation
🔹 Wavelength and Frequency of wave
🔹 Amplitude of magnetic field
🔹 Expression for magnetic field

This question is very important for CBSE Board Exam 2025–26 and also helps in JEE / NEET concepts of electromagnetic waves.
