LIGHT ENERGY

LIGHT ENERGY!

• BY RICHARD BROWN

The Heat Of Light Energy

• Light energy is the ability of light to cause
  changes in matter such as heating matter. For
  example, you can feel light energy change to heat
  energy when the sun warms you up.

3
Natural and artificial light sources.

• Natural light sources are things that are not man
  made but made by themselves. An Artificial light
  source is something man made. For instance
  lightning, fireflies, and stars are a Natural
  light source. Artificial light sources are
  candles, light bulbs, and video games. Light
  comes natural and artificial sources.

4
TRANSPARENT!

• Matter lets most light pass through is called a
  transparent substance. One Transparent device is
  a Triangular prism. A Transparent device lets you
  see clear.

5
TRANSLUCENT

• Translucent only lets some light through. One
  substance that is translucent is sunglasses. When
  light energy strikes matter light energy slows
  down.

6
OPAQUE

• When matter does not let any light through is
  called OPAQUE. AN Opaque devise is a brick, some
  types of wood, and rocks.

THE COLORS OF THE LIGHT SPECTRUM

• The colors of the light spectrum is red, orange,
  yellow, green, blue, and violet. These colors
  have a nickname called roygbv ( red, orange,
  yellow, green, blue, and violet).

WHY WE PAINT THESE THINGS THESE COLORS?

• We paint stop signs red and buses yellow due to
  the fact that it is easier to see. Why
  sweatshirts are blue due to the fact that paints
  and chemicals are in it plus the white color
  makes it see easier.

CONCAVE MIRROR

• A concave mirror is a mirror you dont want to
  reflect light on. When light strikes a concave
  mirror the reflects every where. When light hits
  off this mirror it is unpredictable where its
  going to go.

10
CONVEX MIRROR

• A convex mirror is a flat mirror. This mirror is
  what you want light to reflect off. When this
  mirror gets hit off of light it is predictable
  where the light is going to go.

11
LENSES

• A Convex lens makes you far sighted. A concave
  lens makes you see nearsighted. So if you are
  near sighted then get a convex lens but if you
  are far sighted then get concave lens. This is
  how glasses work.

12
Refraction

• REFRACTION is the bending of light. For example
  if a ruler is in the water it looks like its cut
  in half but, it isnt cut in half it is refracted.
