The purpose of this experiment was to understand the reflection of light on spherical mirrors and how images are formed from them. The experiment was split into 3 sections. The first section was done through Phet lab and was done to showcase how different color light waves were combined to created new colors light waves. The second section was done to show
the reflection of light on a spherical mirror and if an image can be produced. The final section was done through Capstone and was done to show the reflection of light on a concave mirror, specifically if an image can be reflected from one place to another. All data values were then entered into Excel to be analyzed. For our qualitative results, we found that the mixing of light waves does produce different
colors but when all colors were mixed, we found the end color to be white, if the colors were all at 100%. We found that different amounts of red, green, and blue produced different colors. For activity 2, we found that decreasing the object distance increases magnification and that a real image and a virtual image are distinguished by being inverted. For our quantitative results, we found that our percentage error from the experimental value (trendline y intercept value) and the accepted value (actual radius of curvature) was 68% showing that our experimental value was not at all accurate to the actual concave radius of curvature.
