Page 7 - BP1Z 018 Why is the Sky Blue
P. 7

When the sun shines its light




      on the Earth, the light travels



      through the atmosphere



      like ocean waves.









      These light waves are invisible




      to the naked eye, but some of



      the colors they produce can



      be seen and appreciated.
