1. for part 1 of your datasheet, wire up the circuit in fig. 4.3. section 4.2.1. set r to low value (~50ohms) for section 4.2.1 only. what is the resonant frequency of your lc circuit? (1 point) 2. what is the percent difference from the theoretical value of f0 and the observed value you found in question 1? (for l, use the value displayed on your inductor) note: theoretically, f (1 points) 0 = 1 (2π√lc) 3. knowing c and using your observed f0 , calculate l. show your work, and include units throughout. how close is this to the value of l displayed on your inductor? (2 point)

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
