What is Light?

 Introduction:
Without light we can see nothing. Sunlight is by far the most important source of energy on the earth and our entire solar system. Without sunlight, no known type of life could exist on the earth. All plants and animals are depended on light.

Although we can see light, we still have many questions about it. What is it? Can you fill up a bottle with light and use it when you need some? What is light? Is it a substance? Matter? Energy? Wave?  

 
 Project description:
In this project you perform experiments to determine if the light is wave or particle. You will also perform experiments to find out how the light energy changes by distance. 
 Details of this project:
More details or support on this project is available for the members of ScienceProject.com. Material needed for experiments may be obtained locally or purchased online.  You may make your own radiometer as a part of this project; however, for better results you may use a semi-vacuumed glass radiometer (MiniScience.com part#T01800) or a fully vacuumed glass radiometer.
