FAQ

Those interested in the Animated gif electromagnetic wave propagation category often ask the following questions:

### ☑️ What is meant by electromagnetic wave propagation?

In simple words, electromagnetic waves are oscillations produced due to crossing over of an electric and a magnetic field. The direction of the propagation of such waves is perpendicular to the direction of the force of either of these fields as seen in the above figure.

### ☑️ Does amplitude of electromagnetic wave change with propagation?

#### How is the energy of an electromagnetic wave related to its amplitude?

• Explain how the energy of an electromagnetic wave depends on its amplitude, whereas the energy of a photon is proportional to its frequency Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes this energy is obvious, such as in the warmth of the summer Sun.

### ☑️ How does the propagation of an electromagnetic wave occur?

• Electromagnetic Wave Propagation. The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produce a formation that propagates as an electromagnetic wave.

### ☑️ Why is the propagation of an electromagnetic wave important?

• Electromagnetic Wave Propagation. This is true regardless of whether the electric or magnetic vectors are considered, because what matters is the effect of the electric or magnetic fields on the electrons in the material medium (the magnetic field affects those electrons that move in a plane perpendicular to the magnetic field).

### ☑️ Which is true of the propagation of an electromagnetic wave?

• An electromagnetic wave is a wave radiated by an accelerated charge and which propagates through space as coupled electric and magnetic fields, oscillating perpendicular to each other and to the direction of propagation of the wave. Electromagnetic waves are transverse in nature.

From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength.

The electric field vector and the magnetic field vector are perpendicular to each other, and the direction in which the wave propagates (moves) is perpendicular to both of them.
