Journal Entry 9/16

In a completely dark room, I would not be able to see anything. If no light ray is being projected, nothing is reflecting off any object in the room. Sight is a result of a light ray being reflected off of an object, and therefore without light rays, nothing is seen. Light travels in straight lines because it cuts straight through the air, moving from its point of emission to the point at which it will be reflected. A light ray draws your eye to focus on an object, and illuminates it. You can't see objects in a dark room because no light is being reflected off of said object. The inability to see an object in a dark room, coupled with the ability to see an object in a lighted room shows that you can see an object whena light ray enters your eye. Light rays are sent in all directions from an object because you can see an object from anywhere in a room. When we experimented with the laser, Mr. D'amato could see the laser from the front of the classroom, and I could see it from my desk. This means that the light bulb sent out rays from all directions, and these rays reflected off the wall in an equally large array of directions. p
