The spectrum of electromagnetic radiation is comprised of waves or particles that carry different amounts of energy. The visible spectrum is what humans and most animals see. The least energetic range of electromagnetic ... More »

The fundamental source of electromagnetic radiation is the vibrational interaction between an electric field and a magnetic field. This phenomena is driven by the motion of electrically induced particles propagating thro... More »

Electromagnetic waves can travel and transport energy without a medium through which it may travel. This contrasts with mechanical waves, such as sound waves, which cannot travel through a vacuum. If electromagnetic radi... More »

Electromagnetic radiation is energy that comes from a wide variety of sources. It comes in a broad spectrum of wavelengths, frequencies and energies. Scientists break the electromagnetic spectrum into several different c... More »

Electromagnetic waves carry electromagnetic energy, also known as electromagnetic radiation, through matter, empty space, momentum and angular momentum. Depending on their frequency and wavelength, electromagnetic waves ... More »

To reduce the dose of ionizing radiation absorbed from electromagnetic radiation, it is important to minimize the time exposed, be as far as possible from the source and take shelter behind an adequate shield. These thre... More »
