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.
Best Answer: The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430â790 THz. If the shortest wavelength is taken as 400 nm, the maximum frequency is 750 THz. (1 THz = 10^12 Hz)
