Grade 8 Science. Incandescent. “Hot Light. ”. An . object that can be heated to such a high . temperature that it emits light.. Luminescent. “Not Hot . Light. ”. Light . that does not need to be hot to glow. . Bright light story. The farmer was crossing the field at dusk when a bright light was sighted in the sky. Upon reaching the farmhouse, Olson made a telephone call to the sheriff. The farmer grabbed a camera and dashed outdoors to get pictures. The next day the big news report in the local paper was an alleged UFO sighting.. Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. UV . light, which comes from the sun, is invisible to the human eye. .. It . makes black-light posters glow, and is responsible for summer tans — and sunburns. film and video see things in a much more . contrasty. way. . In other words, they cannot cope with the . lighting contrast.  of real life: if you shoot a scene without artificial lights, either the shadows will go completely black or the highlights will go completely white. . Dispersion of light. Visible light = full spectrum . wavelengths range from 400 nm to 700 nm. Different wavelengths have ever so slightly different indices of refraction when passing through materials such as glass, plastic, or water (and probably others). Light. What is light?. . It is the electromagnetic . radiation that can be . perceived . by the human eye. It is made up . of.  . electromagnetic waves.  with wavelengths between . 4 . × 10. -7. Light. Light. Properties and Interactions. What is Light?. Light. is a form of energy emitted by the Sun..  . What is Light?. Light. is a type of energy that travels as an electromagnetic wave.. It wasn’t until the early 19. th. century that light was theorized to behave as something other than a stream of particles.. Isaac Newton proposed the particle theory of light.. Newton’s theory was used to explain the reflection and refraction of light..
