Question

Define electromagnetic waves. write there characteristics​

Answer 1

Answer:

The inherent characteristic of electromagnetic waves is its frequency. According to Maxwell, varying the electric field gives rise to a magnetic field. ... Thus, an electromagnetic wave consists of sinusoidal time-varying electric and magnetic fields, and both the fields are perpendicular to each other.

Answer 2

ANSWER :-

$Definition \: of \: electromagnetic \: waves \: - -$

The combination of mutually perpendicular sinusoidal variations of electric and magnetic fields in direction perpendicular to the propagation of wave.

There are some following characteristics of electromagnetic wave - -

• Transverse in Nature

• No medium required for propagation.

• Uncharged

• Carry energy equally distributed in electric and magnetic field vectors.

• Exert pressure.

• Carry momentum
