How much energy is carried by an electromagnetic wave?
It is clear, from the above, that half the energy in an electromagnetic wave is carried by the electric field, and the other half is carried by the magnetic field. As an electromagnetic field propagates it transports energy.
What is the relationship between electromagnetic waves and electric waves?
so that. Since half the energy in an electromagnetic wave is carried by the electric field, and the other half is carried by the magnetic field, it is conventional to convert the above expression into a form involving both the electric and magnetic field strengths.
What determines the amplitude of an electromagnetic wave?
In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields ( (Figure) ). The wave energy is determined by the wave amplitude. Energy carried by a wave depends on its amplitude.
What is electromagnetic energy?
Electromagnetic energy is radiant energy that travels in waves at the speed of light. It can also be described as radiant energy, electromagnetic radiation, electromagnetic waves, light, or the movement of radiation. Electromagnetic radiation can transfer of heat.
