LUX
OF THE SEVERAL TRANSPARENT SUBSTANCES, THE ONE HAVING THE LARGEST INDEX OF REFRACTION IS THE ONE HAVING CHARACTERISTICS OF WHAT?
THE LIGHT TRAVELS THE SLOWEST
THE DISPLACEMENT OF A REFRACTED RAY OF LIGHT THROUGH A GLASS DEPENDS ON
-THE THICKNESS OF THE GLASS
-THE ANGLE OF ENTRY OF THE LIGHT
-THE INDEX OF REFRACTION OF THE GLASS
WHAT TYPE OF SIMPLE LENS IS THICKER IN THE CENTER THAN IT IS AT THE EDGES?
A POSITIVE OR CONVERGENT LENS
IN A GIVEN MEDIUM, THE COLOR OF A LIGHT WAVE IS DETERMINED BY WHICH FACTORS?

WHEN FIGHTING AN ELECTRICAL FIRE, YOU SHOULD USE WHAT TO EXTINGUISH THE FIRE?
CARBON DIOXIDE (CO2)
IF YOU SWALLOW GASOLINE,WHAT SHOULD U DO?
DRINK A LARGE AMOUNT OF MILK OR WATER AND TAKE 4 TABLESPOONS OF VEGETABLE OIL
HAZARDS OF COMPRESSED AIR?
-CAN INJECT MINUTE FOREING OBJECTS INTO SKIN
