This week we learned about the eye and how it works. We also learned more about refraction and reflection. I learned hat when you see an image your eye filips it and then processes it. I also learne that the light in a triangular prism will stay inside unless you turn off the light. Some light will come out but the rest will continue to reflect around the prisim. We tested this by shinning a laser through the prism. We then drew what we thought would happen. It is important to now this because it tells us that light continues to bounce until the light is turned off. This can be true with any prism.We also learned about the eye and this can help us in life because it tells us how our eye works and shows us what exactly happens when we look at an image.
