Unformatted text preview: calculating the percent error of your measured value. VI-5: Tabulate the data from step V5. 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....
