The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. All EM waves are made up of photons that travel through space until they interact with matter; some waves are absorbed and others are reflected.
Start studying 7 types of electromagnetic waves from largest to smallest. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Visible light is the only kind of electromagnetic waves that are visible, however there are 7 types of electromagnetic waves, or we can call them electromagnetic radiations. Rank based on wavelength, from high to low, they are: Radio wave. Microwave. Infrared Ray. Visible light.
X-radiation is referred to with terms meaning Röntgen radiation. X-ray detectors collect actual photons of X-ray light . Instruments aboard high-altitude balloons and satellites like the Compton Observatory provide our only view of the gamma-ray sky 7 Types of Electromagnetic Waves .

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 ...
The electromagnetic spectrum. Photo: Diagram of electromagnetic spectrum courtesy of NASA.. All the different kinds of electromagnetic radiation are essentially the same "stuff" as light: they're forms of energy that travel in straight lines, at the speed of light (300,000 km or 186,000 miles per second), when electrical and magnetic vibrations wiggle from side to side.
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.
7 types of electromagnetic radiation. Light The visible region of the spectrum is the one most familiar to us, because as a species we have adapted receptors (eyes) that are sensitive to the most intense electromagnetic radiation emitted by the Sun, the closest extraterrestrial source. The limits of the wavelength of the visible region are from ...
Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum. Electromagnetic waves are classified according to their frequency. The different types of waves have different uses and functions in our everyday lives. The most important of these is visible light, which enables us to see.
