 * THE STUDY OF FLASHLIGHTS AND THE AMOUNT OF LIGHT THAT DIFFERENT SOURCES OF LIGHT PRODUCE **

The purpose of this study was to determine if the distance that the flashlight is held effects and determines how much light that the light probe will collect. Visible light, which is commonly referred to as light, is part of the electromagnet spectrum, which ranges from radio waves to gamma waves. A flashlight was placed several different distances away from the light probe it was then turned on. It was determined that when the flashlight was placed 1 cm away from the light probe the light probe collected more light than when farther away. It was concluded that the reason that less light is collected when placed farther is due to the spreading of the light.
 * ABSTRACT **

An improvement to this experiment would be to be more precise when measuring the amount of time that the flashlight is left on. This way, the exact amount of time that the flashlight is left on for would be correct. The amount of time that the flashlight is left on for would be more controlled, and would then not affect the results of the experiment. In order to expand the experiment it could be interesting to see whether the temperature surrounding the flashlight affects the amount of light that the flashlight produces.
