Electromagnetic waves are produced by accelerating electric charges or changing magnetic fields. Examples include light waves produced by the sun, radio waves from a radio antenna, and X-rays from medical equipment.
EM waves stand for Electromagnetic waves.
Electromagnetic waves are called EM waves because they are composed of oscillating electric and magnetic fields. These fields propagate through space, carrying energy with them. The combination of electric and magnetic fields gives rise to the term "electromagnetic."
The key difference between the E field and H field in electromagnetic waves is that the E field represents the electric field, which is responsible for the electric force on charged particles, while the H field represents the magnetic field, which is responsible for the magnetic force on charged particles. In electromagnetic waves, these fields are perpendicular to each other and oscillate in phase.
High frequency electromagnetic waves have more energy than low frequency waves. This is because the energy of an electromagnetic wave is directly proportional to its frequency: E=hf, where E is energy, h is Planck's constant, and f is frequency.
Electromagnetic radiation consists of waves with different wavelengths and frequencies. The frequency and energy of electromagnetic radiation are directly proportional—higher frequency waves have higher energy. This relationship is described by the formula E=hf, where E is energy, h is Planck's constant, and f is frequency.

EM is just shorthand. E for electro, M for magnetic. Electromagnetic. Pretty cool huh?

Electrical energy, E = hf.

The sun shines on us, and light is e-m waves.
Electromagnetic waves vary in frequency, wavelength, and energy. These properties determine the type of electromagnetic wave, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of electromagnetic wave has unique characteristics and uses.
The transfer of energy by electromagnetic waves is called electromagnetic radiation. Light, radio waves and X-rays are a few other examples of this radiation phenomenon. The Transfer process is the "flow" of particles from one location to another. The best visual example is the transfer of "heat" from one source to another.

No, consider a coil of wire conducting a constant current. There will be a static magnetic field around it, but no electromagnetic waves with E X H = P
