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.
