5)Use the metric scale on the optics bench to measure the distance between the filament and thecenter of the ray table directly. This will be your known value. Determine the percent errorbetween the known filament distance, and the back-projected distance from your drawing.3/3/2017 12:11 PM
Question 6.Is the ray bent when it passes into the lens perpendicular to the flat surface of thelens? Explain.
Question 7.What relationship holds between the angle of incidence and the angle of reflection?
Question 8.Do the rays seem to follow a straight line into the mirror?
Question 9.Based on your results, what is the relationship between object and image distance forreflection in a plane mirror?
Question 10.Where is the paper when the image is the sharpest?
Question 11.Is this result approximately consistent with the mirror equation (where dois the object distance 10 cm, diis the image distance, and fis the focallength of the mirror)?
Yes , because it represent the original length of the image reflected AnalysisConclusionThroughout the experiment, we saw several concepts concerning interference, light travels in a straight line. We observed the change in direction of light when it encounters a reflective surface.As light propagates through a different medium, its speed changed. The results fit expectations. The percent error for the lens was only 10.3%. The R-squared valuesfor Snell’s Law were above 0.99, which indicates a strong linear relationship. the mirror verified the Law of Reflection, since angles of incidence and reflection were equal for the most part. Any error can be explained by issues with measurement and can be improved with more accurate datacollection or more trials. Finally. Thy overall experiment was successful 3/3/2017 12:11 PM
