em wave is generated by photons which emitter the energy in the form of light
The frequency of an electromagnetic (EM) wave is directly proportional to its energy. This means that as the frequency of the EM wave increases, so does its energy. Conversely, a decrease in frequency leads to a decrease in energy of the EM wave.
radio wave
A moving charge (such as an electrical current) generates a magnetic field at right angles, true, but this field is stable and unchanging. An EM wave is only produced by a changing movement, for example an AC current. The condition would be that the field will change (and produce a wave) only if the current changes.
A charged particle produces an electromagnetic wave by accelerating back and forth. As it moves, the changing electric field generated produces a changing magnetic field, and vice versa. These changing fields propagate through space together, creating the electromagnetic wave.
EM waves stand for Electromagnetic waves.
The energy of an electromagnetic (EM) wave is determined by its frequency and amplitude. The higher the frequency, the higher the energy of the wave. Additionally, the amplitude of the wave also plays a role in its energy content.
They're the same. EM stands for electromagnetic.
visible light
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
No, it's not. EM wave is a single unit, and it cannot exist without ether of components (electric, magnetic).
