Japanese intelligence about American productive potential was about as limited as German knowledge of the Soviet Union.

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.
Definition of UVB. : radiation that is in the region of the ultraviolet spectrum which extends from about 280 to 320 nm in wavelength and that is primarily responsible for sunburn, aging of the skin, and the development of skin cancer.ADVERTISEMENT.VB. noun \-ËbÄ\. : radiation that is in the region of the ultraviolet spectrum which extends from 280 to 320 nm in wavelength and that is primarily responsible for sunburn, aging of the skin, and the development of skin cancer.
