Which of the following is NOT the characteristic of electromagnetic waves?

CONCEPT:

• Electromagnetic waves or EM waves: The waves that are formed as a result of vibrations between an electric field and a magnetic field and they are perpendicular to each other and to the direction of the wave is called an electromagnetic waves.
• The accelerating charged particle produces an electromagnetic (EM) wave.
• A charged particle oscillating about an equilibrium position is an accelerating charged particle.
• Electromagnetic waves do not require any matter to propagate from one place to another as it consists of photons. They can move in a vacuum.

Properties of electromagnetic waves:

• The electromagnetic waves are neutral.
• Propagate as a transverse wave.
• They move with a velocity the same as that of light i.e 3 × 108 m/s.
• It contains energy and also contains momentum.
• They can travel in a vacuum also.

Characteristics of Electromagnetic waves:

• The accelerated charge particles are the source of electromagnetic waves.
• Electromagnetic waves are transverse in nature as they propagate by varying the electric and magnetic fields such that the two fields are perpendicular to each other.
• Electromagnetic waves have constant velocity in vacuum 
• Electromagnetic wave propagation does not require any material medium to travel.
• Electromagnetic waves follow the principle of superposition.
• Electromagnetic waves are not reflected by an electric or magnetic field.

Explanation:

• Hence we can see that Moving charges are not responsible to produce electromagnetic waves,
• Instead Accelerated charges are responsible to produce electromagnetic waves.
