Japanese intelligence about American productive potential was about as limited as German knowledge of the Soviet Union. In Tokyoâs view, if Japanese naval forces took out the American Pacific carriers at Pearl Harbor, there was simply no way for America, at least in the immediate future, to contradict any of their Pacific agendas.
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm (30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays. UV radiation constitutes about 10% of the total light output of the Sun, and is thus present in sunlight.
Ultraviolet. Ultraviolet light is in the range of the EM spectrum between visible light and X-rays. It has frequencies of about 8 Ã 10 14 to 3 Ã 10 16 Hz and wavelengths of about 380 nm (.000015 inches) to about 10 nm (0.0000004 inches). UV light is a component of sunlight; however, it is invisible to the human eye.aves and fields. EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.
