Title: Light


1
Light
  • Light is something that we use to see with. It
    is a wave that travels through space/the air.
  • What we know as light is actually a small part of
    something called the Electro-magnetic Spectrum
  • This small part is only what we are able to see.
  • The other parts are just like the light we see,
    but invisible to us.
  • Like a dog whistle except with light not sound.
