Light
Light is everywhere, and
without light, life would not exist. Light waves travel from place to
place. Light is a form of energy that can be seen when it is reflected off the
surface of an object. It is visible to the human eye and is responsible for the
sense of sight. Light waves travel through the air from place to place and do
not carry matter. Light travels at a speed of 186,000 miles per second. Light
is unable to travel through solids, but it can travel through liquids and
gases.
