For the Element of Harmony, see the appropriate section of the Elements of Harmony article. My Little Pony Friendship is Magic possesses many fantasy elements. A prominent one is the use of magic by ponies and other creatures such as changelings. Throughout the show, Earth ponies tend to crops and care for plants and animals, particularly in Winter Wrap Up, Fall Weather Friends, and Hearth's Warming Eve.
Visible light is merely a small part of the full electromagnetic spectrum, which extends from cosmic rays at the highest energies down through the middle range (gamma rays, X- rays, the ultraviolet, the visible, the infrared, and radio waves) all the way to induction-heating and electric-power-transmission frequencies at the lowest energies.
Visible spectrum. The visible spectrum is a very small portion of the electromagnetic spectrum that can be seen by human eyes. This is shown in the figure below, which is not to scale. The exact boundaries of each type of wave are not precisely defined and often different authors have slightly different values.he limit between ionizing and non-ionizing radiations is located somewhere in the UV region, but it's not clearly defined and somehow fuzzy. A photon energy of 10 eV (corresponding to 124 nm) is often considered the threshold between ionizing and non-ionizing radiation, but there is no consensus on this topic.
