Electromagnetic Waves An electromagnetic wave is a transverse wave, with the electric and magnetic fields oscillating a right angles to each other Electromagnetic Spectrum The electromagnetic spectrum is the full range of frequencies
or wavelengths which a wave can oscillate at. The wavelength is the
distance a wave will travel during one full cycle or oscillation What
our eyes detect as visible light are electromagnetic waves with a wavelength
between 750nm and 400nm. |

| RM Cybernetics: Good day! I am a student who had a research work on the latest application of Electromagnetics on the differents field such as space exploration, aerospace, medicine, engineering etc. I just want to ask you for some information you could give me about the latest applications of electromagnetics. Please send your message to my email address Email Address Removed I am hoping for your kind consideration. Respectfully Yours: Kumiho | |

A
changing electric field can give rise to a changing magnetic field,
and vise versa. In an electromagnetic wave, the electric and magnetic
fields keep each other going so that it can propagate through free space.
The frequency of this oscillation determines the energy that the wave
will carry. Higher frequency waves such as Gamma rays carry significantly
more energy than longer waves like radio waves or visible light. The
energy is calculated using the formulae E=hf. Where 'E' is
energy, 'h' is planks constant, and 'f' is the frequency.
