Period 1

Today in class we light up a candle and put it next to the wall, we drew a ray diagram of where the light was going to go. We drew the rays of where the rays from the candle were going. We wrote on the board that the light went from the candle and went everywhere and it bounced off the wall and towards us. This happend because there was light shining off the wall from the candle that we could see.

Next we had the light and a piece of cardboard, there was a hole in the piece of cardboard. When the candle was shining there was a dot on the wall from the candle through the cardboard. The dot was the image of the candle uside down. We drew up how this happend with the rays from the light. Every table in the class had a different idea of how the candle was upside down when it went through the little hole through the cardboard. We said that the light from the bottom went through the hole and went to the top of the shadow on the wall.
