Physics, Monday, Class #8, Period 4
"Afternoon, everyone," Sam said from her perch on the desk. "It's good to see you all after the parental invasion this weekend. Rodney, I hope you found your sister."
"Today we'll be talking about light. The three primary properties of light are intensity, frequency or wavelength, and polarization."
"The human spectrum of visual is from red to violet, which can be seen individually when you look at white light through a prism," she explained, writing ROYGBIV on the board, near the equations, "but ultraviolet and infrared are just as important for human survival, as well as the survival of the planet. A red shift--where suddenly infrared light is visible to the human eye--is fatal after a remarkably short period of time. Not just to the humans, but to the things that humans depend on for food, such as plants and animals."
Not their shining moment of Stargate use, no.
"Light, obviously, can come from a number of different sources, although the primary source of light on this planet is obviously the sun. Light, which is thought to travel in waves, can be refracted, or bent through the use of optics. We'll get into theories of how light works next week. For now, I just want you to get used to seeing it and measuring it--there are prisms, magnifying lenses, and telescopes for you to work with, as well as different light sources, so you can see how the spectra of light differ. There are also spectrometers, so you can measure the light and try to predict its behavior, if that's your thing."
