Electromagnetic waves (EM) – Electromagnetic wave (Chapter 11): IIT JEE Class 12 Physics.
Here we describe the topic as electromagnetic waves form class 12 physics iit jee.
We can start from,
What are Electromagnetic waves?
Electromagnetic (EM) waves are the waves which are related to both electricity and magnetism.
Electromagnetic (EM) waves are the waves which are coupled time-varying electric and magnetic fields that propagate in space.
Waves associated with electricity and magnetism and as they are varying with time they both will give rise to electromagnetic waves.
Electromagnetic equations emerged from Maxwell’s equations.
Maxwell found these EM waves have so many special properties which can be used for many practical purposes.
Time-varying electric field + Time-varying magnetic field = Electromagnetic waves.
Properties of Electromagnetic Waves:
Electromagnetic wave oscillating electric field and magnetic fields.
The electric field, magnetic field, and direction of propagation of electromagnetic waves are all mutually perpendicular.
Electromagnetic waves carry energy.
Energy is carried in oscillating electric and magnetic fields.
The energy carried in the electric field = energy carried in the magnetic field.
All the above-mentioned topics are described in an interactive and efficient manner so that the students could easily understand them.
