course phy 202 Here is some labs that I had failed to turn in! The date for these labs was 02/26/07 There were three candles set up next to a beaker of water. They were set up so that no one candle's refractions upset another candle's refractions. The diameter of the cylinder was 16.7cm The candle was 3.6 cm away from the cylinder. When measuring the reflection from the edge of the cylinder our goal was to try to get the reflection to be as even as possible. By even I mean that we wanted the reflection to stay the same width uniformly. This is not entirely perfect but it was as close as I could get to uniform. Distance from edge of cylinder Width of reflection 5cm 11cm 10cm 10.5cm 15cm 10.5cm 20cm 10.5cm 25cm 10.5cm 30cm 10.5cm The candle flame was 5cm high and 3.6 cm away from the cylinder. Also since I measured from the edge of the cylinder, I would probably have to take half of 16.7cm to get the radius and add that to each of my measurements that way I would be measuring from the center of the cylinder. We then took 1 lens and tried to make a spotlight with it. Distance from Diameter of lens to candle the spotlight 5.2cm 3.8cm 10cm 5.2cm 3.3cm 20cm 5.2cm 3.0cm 30cm 5.2cm 3.2cm 40cm When we tried to get a good reflection of the flame on the wall we sort of ran out of time. It was hard using the two lens and trying to get an accurate reflection. Our best reflection was 21cm wide. It was 3.1 meters from the image to the candle. It was 2cm from lens to lens. The 2nd lens was 2cm away from the candle. It was also difficult to get a good reflection because of our crappy lens. It had gunk on it and often distorted the reflection. "
