Sources and Nature of Light worksheet File
... The different ways of producing light depend on
the different ways electrons can be forced to
move to higher energy levels in their atoms.
Although the electrons may be moved to higher
energy levels in different ways, the light is
always produced in the same way.

Class notes on LIGHT
... –Transparent object: light passes through the object and is seen on the other side.
–Translucid object: a portion of light goes through the object (other side is not visible).
–Opaque object: light does not go through (completely blocked).

... We cannot see ultraviolet light energy (UV) because its wavelengths are too short for our eyes to
detect this wavelength range. How do I know it exists?
UV causes sunburns. Our skin is sensitive to this kind of light because our skin absorbs
this energy. After the energy is absorbed, it can make o ...

Doctor Light (Arthur Light)
Doctor Arthur Light is a supervillain appearing in comic books published by DC Comics. He is the third individual to have adopted the persona of Doctor Light, after a Golden Age foe of Doctor Mid-Nite and Arthur's associate Jacob Finlay. Light, a long-time enemy of the Teen Titans and the Justice League, has been portrayed both as a serious menace and as a company in-joke for incompetent supervillains. His stint as Doctor Light is concurrent with that of a superheroine using the same name and nearly identical costume, Kimiyo Hoshi. In 2009, Doctor Light was ranked as IGN's 84th Greatest Comic Book Villain of All Time.
