10 Αυγ 2016 · What is Electromagnetic energy? Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light.
Electromagnetic energy gets released when an external force accelerates an electrical charge. The acceleration generates a wave of alternating magnetic and electric fields that detaches from the charge and moves independently in the medium.

12 Σεπ 2023 · Electromagnetic waves are like invisible magic waves that can travel through the emptiness of outer space. They are created when electric charges wiggle back and forth. This wiggling makes electric and magnetic fields that move together in waves.
8 Μαρ 2022 · The electromagnetic spectrum is the name for the different forms of light that are given off by objects in the Universe. Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays are all types of light, but with different energies!
Electrical energy is moving energy. It is the movement of tiny particles called electrons and protons. Electrical energy can be seen in nature in a bolt of lightning, which is a large number of electrons flowing through air all at once. People have learned how to produce electrical energy and control it.
