Question

Electromagnetic waves do not transport:
(A) energy
(B) charge
(C) momentum
(D) communication signals

Answer 1

Hint Electromagnetic waves are otherwise called EM waves that are produced by an electric field that interacts with the attractive field. It can likewise be said that electromagnetic waves are the piece of electric and attractive fields. Electromagnetic waves are arrangements of Maxwell's conditions, which are the principal conditions of electrodynamics.

Complete step by step solution
Generally, an electric field is created by a charged molecule. A power is applied by this electric field on other charged particles. Positive charges move toward the field and negative charges move in the opposite direction of the field. The Magnetic field is delivered by a moving charged molecule. A power is applied by this magnetic field on other moving particles. The power on these charges is consistently opposite to the course of their speed and it just alters the direction of the speed, not the magnitude of the speed.
The electromagnetic waves are able to carry the digital data by encoding the data and transmit the data over an analogue carrier by modulating the digital data. Once the modulation of the data is done, it is passed by the antenna. The receiver will capture the waves and demodulate the waves and get the data. The electromagnetic waves are transferred when they get some energy, so that the electromagnetic waves transport energy, if the energy is transferred by the electromagnetic waves then the momentum is also transferred. Then the electromagnetic waves transport the data which means communication signals.

Hence, the option (B) is the correct answer.

Note The electromagnetic waves will obey the speed equation, $c = f\lambda $, where $c$ is the speed, $f$ is the frequency and the $\lambda $ is the wavelength. The product of the frequency and the wave length is equal to the speed of the wave. The speed of the wave is directly proportional to the frequency and the wave length.
