El espectro electromagnético

Electromagnetic waves can propagate in space without a medium, using electric and magnetic fields. These fields oscillate perpendicularly and form transverse waves. The electromagnetic spectrum includes a wide range of wavelengths, from radio waves to gamma rays. Natural sources like stars and artificial sources like microwaves emit electromagnetic radiation. As wavelength decreases, frequency and energy increase, leading to ionization, where atoms become charged ions. Electromagnetic radiation is crucial for survival.
