2. Write down the properties of electromagnetic waves.
Answers
Answer:
They are transverse in nature. They consist of oscillating electric (E) and magnetic (B) field vectors at right angles to each other and at right angles to the direction of propagation of the wave. They can travel through a vacuum.
Explanation:
Electromagnetic waves are composed oscillating electric and magnetic field at right angles to each other.
Properties
Electromagnetic waves are propagated by oscillating electric fields and magnetic field oscillation at right angles to each other.
These waves travel with speed 3×10
