  • What kind of object allows some light to pass through it and allows you to see a blurry or not so clear view of what is on the other side of it?
    Translucent
  • If you filled a glass with water and struck it with a metal spoon, how could you change the pitch?
    If you add more water, the higher the pitch will be. If you take out water, the lower the pitch will be.

  • On a hot summer day, a black shirt gets hot because light is _____________
    attraction
    reflected
    refracted

  • What kind of object allows all light to pass through it, and you can see through it?
    Transparent
  • When you hold up a prism to a light source, what happens to the light when it passes through and leaves out the other side of the prism?
    It bends after it enters the prism and separates into the colors that make up white light.
  • When a flashlight is aimed at a mirror or other smooth and shiny object, what happens to the light after if first hits the mirror?
    It bounces off at the same angle that it hit the mirror.
  • A guitar string makes a higher pitched sound when you tighten the string. Why?
