Different states of photons and wave properties lead to different types of electromagnetic waves. The video explains the fundamental concepts of electromagnetism. The electromagnetic spectrum is the range of all electromagnetic radiation in terms of its wavelengths and frequencies.
Introduction to the Electromagnetic Spectrum - NASA Science
2016年8月10日 · 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. A radio detects a different portion of the spectrum, and an x-ray machine uses yet […]
Electromagnetic Spectrum - Introduction - Imagine the Universe!
2014年11月14日 · The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.
Electromagnetic spectrum | Definition, Diagram, & Uses | Britannica
4 天之前 · electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.
Electromagnetic radiation - Wikipedia
Electromagnetic-type ionizing radiation extends from the extreme ultraviolet to all higher frequencies and shorter wavelengths, which means that all X-rays and gamma rays qualify. These are capable of the most severe types of molecular damage, which can happen in biology to any type of biomolecule, including mutation and cancer, and often at ...
