Reflection Of Magnifying Glass

Observation – Magnifying glasses are normally made of convex lenses. A convex lens is thin on the outer edges and are thicker in the center. They bend light inwards towards a focal point. They can be used to make objects appear larger than they actually are. This is accomplished by placing the lens close to the object or item. In this way, the light rays are bent towards the center of the lens creating a focal point. When the bent rays hit the retina, it will make the object appear larger than it actually is. The distance the lens are from the surface of the item or object affects the size of the focal point. The focal point of the lens are also determined by the curvature of the lens too. Many people have used a magnifying glass and sunlight …show more content…

According to this graph, the color of paper that took the least amount of time to create a hole is the black colored paper whilst the color of paper that took the longest time to create a hole is the red colored paper. Based on the graph, it is clear that each of the colors are tested five times. From what can be seen from this graph, there are no trials that go above a minute. The range that has the most trials in it is around the 17 to 20 second range because there are two 17 seconds, three 18 seconds, one 19 seconds, and one 20 seconds. The graph shows that the shortest amount of time it takes to create a hole is 5 seconds for the black colored piece of paper whilst the longest amount of time it takes to create a hole is 23 seconds for the red colored piece of paper. There is an 18 second difference between the shortest time and the longest time which is the black paper and the red paper. The mean was 8 seconds for the black piece of paper, 19 seconds for the red piece of paper, and 15 seconds for the blue piece of paper. This shows that the black colored paper is the fastest and the red takes the longest, and blue is somewhere along the middle between red and black. However, the red and blue colored pieces of paper were fairly close in terms of seconds, so blue isn’t that much less than …show more content…

The data that was collected supports the hypothesis because in the hypothesis, it was stated that the black colored piece of paper would create a hole faster than the red or blue pieces of paper. This is because the black colored piece of paper absorb all wavelengths of light whilst the red and blue pieces of paper reflect off one wavelength of light. The data collected supports this because based on the graph and analysis, the range that has the most trials in it is around the 17 to 20 second range, and the trials in that range are the red and blue pieces of paper because they both reflect off one wavelength of light, therefore they both take around the same time to create a hole. The data also shows that the black piece of paper takes the shortest amount of time to create a hole because the shortest amount of time is at 5 seconds and the longest amount of time is 12 seconds, which are both shorter than the other two colors of paper’s trials. Using the graph, it is also clear that the black colored piece of paper absorbs energy the fastest because the grey bars are the mean, and the black colored piece of paper was at 8 seconds whilst red and blue are 19 and 15 seconds, meaning that the black colored piece of paper absorbed energy the most effectively. This shows that the data that was collected supports the
