Light Powr Point

  1. 1. LIGHT!!! And all about it!
  2. 2. Light How Fast is it? What is Light? Some Other Stuff about light Light travels about 299,792,458 meters per second. Electromagnetic radiation that has a wavelength in the range from about 4,000 to about7,00 RED Galileo Galilei measured the speed of light.
  3. 3. HOW FAST DOES IT GO? Light travels 299,792,458 meters per second
  4. 4. WHAT EXACTLY IS LIGHT? The sensation of perceiving light; brightness
  5. 5. SOME OTHER INFO Sir Isaac Newton was the first person to really focus on light. In one second, light can go around the earth 7 times! Galileo Galilei attempted to measure the speed of light. Light goes from the sun to the earth in about 8 minutes.
  6. 6. WHAT LIGHT COMES FROM Light can come from the sun, electricity, friction (which creates a spark), and a flashlight .
  7. 7. A summary about light. Light can carry both energy and information. It both is the way the sun delivers energy to the world, making life possible, and it is a very important way that we learn about the world, through our sense of sight. Part of the information content of light is just the direction it is travelling -- light travels in straight lines, so that when we see a bird in a certain direction, we usually assume that there is a bird there. But lenses and mirrors are devices to change the direction light is travelling.
