Ultraviolet not necessarily coincide; for example one applied physics publication used a boundary of 190 nm between hard and soft UV regions. Very hot objects emit UV radiation (see black-body radiation). The Sun emits ultraviolet radiation at all wavelengths, including the extreme ultraviolet where it crosses into X-rays at 10 nm. Extremely hot stars emit proportionally more UV radiation than the Sun. Sunlight in space at the top of Earth's atmosphere (see solar constant) is composed of about 50% infrared light, 40% visible light, and 10% ultraviolet light, for a total intensity of about 1400 W/m in vacuum. However, at ground
The Invisible Man (1975 TV series) effect of his work is the ability to turn objects invisible, and tries to find medical applications for his invention. He discovers that objects that are made invisible reappear after a few hours, and on living test animals the collars they wear re-appear before the living cells themselves. Obsessed by his invention, Westin decides to become invisible himself, in part to prove that a human can survive the process, and also to test a serum he has developed to reverse the invisibility. He reveals the process to his boss, Walter Carlson (Jackie Cooper), who is initially unimpressed by what he
