I scanned this picture.

The whole thing was easy because we have done this so many times before.

History of discovery in light and vision continued

Euclid was a greek mathmatician who wrote many things, including works on perspective and on geometry. He described how things get smaller as they get farther away. He also wrote on perfect numbers and prime numbers. His writings showed that perspective is in everyday life and everywhere we look.
Empedocles was a greek philosopher who was best known for his work with four elements. He suggested that everything in the universe was made up of 4 elements; water, air, earth, and fire. The interesting story about him was that he threw himself into a volcano believing that he was immortal. He believed that light traveled in a straight line and at a very high rate of speed.
AlHazen studied optics and made very big contributions to the principles of optics. He wrote the Book of Optics and studied binocular vision. He probably built off of Euclid"s idea of perspective. He also studied how light broke up into different colors and he said that light rays were streams of energy particles traveling in straight lines.
Isaac Newton invented the refracting and reflecting telescope. He developed a theory that a prism decomposes white light to all the colors of the spectrum. He studied refraction and fixed the problems of the refracting telescope by make a reflecting telescope. He said that colored light did not change its properties. He believed that light was a stream of particles just like Alhazen.

In a completely dark room we wouldn't be able to see anything. There wouldn't be any light rays to bounce off of anything to go back to our eyes. Nothing would be visible, even though our eyes would be much more sensitive to light. Our classroom wasn't completely dark otherwise we wouldn't be able to see anything at all. For a room to be completely dark, no light rays can enter the room. We couldn't totally seal off the room and make sure no light comes in.

The image is really there but there is no other orange in the mirror or behind the mirror. I wouldn't agree with him because the image of the orange is really there. I would try to convince him that it was really there because no matter what you do it will always be there. The image cannot be an illusion because it is always there. Linda's idea of the image being on the surface is not reality because when we performed the experiment we showed that the image is behind the mirror. It is in the exact same spot as in front of the mirror only opposite and in the back of the mirror. I would show her that when rulers are pointed at the image and are connected, where they intersect is where the image is. It is not on the surface of the mirror but behind it.

review of light fantastic

The movie really showed how the study of light and where it comes from evolved. The fact that people really wanted to know how they see things and how light travels really shows that people wanted to explain life. The part that showed why things appear smaller, farther away was interesting to me. I never really thought how the size of something close directly compares to the size of something far. The movie also showed how the understanding of how light works evolved to the current understanding of light rays and how they move in a straight line.

Jounal Entry 10/5

The things we've learned in our class can easily be connected to the real world. For example, when i look into a puddle after it has rained and see the reflection of the things around me. Its because of the rays bouncing off of the objects to the puddle and bouncing into my eye. Another example is when i wake up at night i can see things in my room because my eyes have adjusted to the darkness. That's because of my pupils expanding so that more light rays can come into my eyes. All the explanations make sense because of the way light rays act normally.
