1. Have you ever tried aiming a flashlight at a distant star on a dark night? Were you able to follow through the path of the light to the star you've pointed? 2.(Before doing this simple demonstration, it would be more effective if the room could be darkened so that the light would be more visible) a. Get a flashlight and aim it at a distant wall or at the ceiling. Did the light form a straight line without blockage? b. Place your hand in front of a flashlight beam. Observe again the light -Did your hand stop the light? Can the light bend around your hand and shone onto th wall? Do you think that light travels in a straight line or in a curve line?​
