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.
UV (Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays, with a wavelength falling between 400 and 10 nanometers. This electromagnetic radiation is not visible to the human eye, because it has a shorter wavelength and higher frequency than the light our brain perceives as images.
