PHY-152 MP3 Manual Addendum VI-For the Report VI-2a: Determine the refractive index, n, of the glass plate using the data from section V2(a) and equation 3. VI-3a: Tabulate the data from step V3(a), including columns for 1/o and 1/i. Using Excel, plot 1/i vs. 1/o. Using LINEST, determine the intercept. Now calculate the experimentally determined focal length. Compare the manufacturers stated focal length fall within the value just calculated. VI-3b: The theoretical value of m is given by i m o = . Calculate m from your data of step V3(b) using both the image data and the locations of the object/lens/image. Compare these two numbers. VI-4: Compare the measured and stated focal lengths of the concave mirror from step V4 by calculating the percent error of your measured value. VI-5: Tabulate the data from step V5.

Unformatted text preview: Plot the ratio I/I vs. φ . Malus’s law predicts that : 2 cos I I φ = . On the same figure plot 2 cos vs. . Do your measurements follow Malus’s law? VII-Questions VII-1: Using the information of section V2(a), calculate the total uncertainty, σ n in the measurement of the refractive index of the glass plate. VII-2: Assume that you have a mixture of unpolarized and polarized light propagating in the same direction with percentages P u for the intensity of the unpolarized and P p for the intensity of the polarized light. P u + P p = 100 Describe a method of determining P u and P p using a single polaroid sheet and a photometer. VII-3: The images formed by lenses appear colored while this is not true in the case of mirrors of any curvature. Explain why this is so....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
