[Figure1]

You have loads of fans, celebrity friends, and much, much more.  But when you're on stage performing? The intense lights nearly blind you and you need to squint your eyes to see anything! Intensity is just one property of light. 

As we know, light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. There are many properties of light and as these change, the way we see the light changes too.

Creative Applications

  1. How does the intensity of light change depending on the size of the bulb?
  2. Propagation direction is the direction in which a wave travels. What would you make the propagation direction to make it not too bright in your face?
  3. How would you polarize your stage light?
  4. How do the properties of light change as the color of the light changes?
