mass a amount of matter in an object.
volume the amount of space an object take up.
weight on earth a measure of the measure of the force of gravity between earth and an object.
density a measure of how tightly packed matter is the amount of mass conteined in a given volume.
buoyancy the upward push on an object by the lighid or gas the object is placed in.
conduct allow heat or electricity to flow through readily.
insulate not allow heat or electricity to flow through readily.
illustrate
electromagnetism the production of magnetism by electricity and the production of electricity by magnets .
electromagnetic spectrum
all the wavelengths of visible and invisible light in order from short gamma rays to long radio.
laser a device that produces a thin stream of light of just a few clothes wavelengths.
illustration
plasma is a fourth state of matter.manyliguid and gas place teach that there are three states of mater,solid,but thre are actually four,the four is plasma.

INTRODUCTION
HOW LONG DOES IT TAKE TO SEE LIGHT WHEN YOY TURN ON A LQAMP IN A DARKENED ROOM`HOW LONG DOES IT TAKE FOR LIGHT FROM A LAMP AT THE END OF A LONG HALLWAY TO REACH THE OTHER END`.
INVISIBLE LIGHT IS SINCE MAXWELL`S WORK, SCIENTISTS HAVE FORMED ANOTHER IDEA OF HOW LIGHT TRAVELS. RATHER THAN AS A SMOOTH VIBRATING WAVE, PERHAPS LIGHT TRAVELS AS TINY BUNDLES OF ENERGY. SCIENTISTS CALL THE BUNDLES PHOTONS.
TYPE OF LIGHT
RADIO WAVES ARE THE LONGEST WAVES OF THE ELECTROMAGNETIC SPECTRUM. YOU DO NOT SEE EHEM.
RADAR RECALL THAT SOME ANIMALS, SUCH AS BATS AND WHALES, SEND OUT SOUND WAVES WITH A HIGH FREQUENCY.
MICROWAVES A MICRO WAVE OVEN USES ELECTROMAGNETIC WAVES, TOO. MICRO WAVE ARE SHORTWAVE RADIO WAVES.
INFRARED LIGHT JUST BEYOND RED ARE NEXT TO VISIBLE RED WAVES IN THE SPECTRUM.
ULTRA VIOLET LIGHT LIGHT IS MADE UP OF WAVES JUST SHORTER THAN VISIBLE VIOLET LIGHT ON THE SPECTRUM.
DESCRIPTION
INVISIBLE LIGHT DIVIDED IN
RADIO WAVES
RADAR
MICRO WAVES
INFRARED LIGHT
ULTRAVIOLET AND OTHERS THAT I DONT MENTION.
PICTURE
CONCLUSION
I LEAR THAT INVISIBLE LIGHT TRAVELS IN MANY
WAVES EXAMPLE RADIO WAVES, RADAR AND OTHERS
AND INVIBLE LIGHT IS TRANSPARENT YOU DONT SEE
IN SIMPLE SEE AND LIGHT TRAVELS WAVES AND STRAIGHT-LINE.
OPAQUE COMPLETELY BLOCKING LIGHT FROM PASSING THROUGH.
TRANSPARENT LETTING ALL LIGHT THROUGH,SO THAT OBJECTS ON THE OTHER SIDE CAN BE SEEN CLEARLY.
TRANSLUCENT LETTING ONLY SOME LIGHT THROUGH, SO THAT OBJECTS ON THE OTHER SIDE APPEAR BLURRY.
POLARIZATION ALLOWING LIGHT VIBRATIONS TO PASS THROUGH IN ONLY ONE DIRECTION
REFRACTION THE BENDING OF LIGHT RAYS AS THEY PASS FROM ONE SUBSTANCE INTO ANOTHER.
CONVEX LENS A LENS THAT CURVES OUTWARD, IS THICKER AT THE MIDDLE THAN AT THE EDGES, AND BRINGS LIGHT RAYS TOGETHER.
CONCAVE LENS A LENS THAT CURVES INWARD , IS THICKER AT THE EDGES THAN AT THE MIDDLE, AND SPREADS LIGHT RAYS APART.
BIOLUMINESCENCE LIGHT PRODUCED BY LIVING ORGANISMS.
LIGHT RAY A STRAIGHT-LINE BEAM OF LIGHT AS IT TRAVELS OUTWARD FROM ITS SOURCE.
LAW OF REFLECTION THE ANCLE OF AN INCOMING LIGHT RAY EQUALS THE ANCLE OF THE REFLECTED RAY.
CONCAVE MIRROR A MIRROR THAT CURVES IN ON THE SHINY SIDE.
CONVEX MIRROR A MIRROR THAT CURVES OUT ON THE SHINY SIDE.
