Michael Bowen 34186802 Lab MP3 V-2a) In this part of the lab, we find the refractive index (n) of the glass plate using our measurements of the thickness of our glass plate (d) and the radius of our dark circle (R). We use equation 3 in Excel to find n. V-3a) For this part of the lab, we plot 1/i vs. 1/o, determine the intercept using the least squares fit, calculate f, and find the percentage error.

We used a lens with f=48mm and set the object-lens distance o=100mm. We then measured the length (L’) of a particular length (L) of the object and used those measurements to find the

We calculated the focal length of the curved mirror using the formula: f=I/2, and compared it with the given focal length (F). We then determined our percentage error. F(mm) I(mm) f(mm) %Err 25 60 30 20 V-5) In this part of the lab, we plotted the I/I o vs. φ against Malus’s law, I/I o =cos 2 φ, vs. φ and compared the two graphs. We used an incandescent source and a Polaroid on a component carrier as a source of polarized light and set the polarizer angle (φ) to different angles in order to get measurements for I(φ)....
