How did you disprove the idea that each point on the light bulb emits one light ray? Describe how you used this idea to make a prediction that did not come true.
The idea that each point on the light bulb emits only one light ray was dis proven when a layer of tin-foil with a pin hole at the top covered the light bulb in the dark room. When the light bulb was turned on, various amount of light beams were shooting out in different straight directions from the pin hole. This experiment proved that the light bulb emitted more than one light ray.
