Question
First 3page is just explanation for lab experiment. I get some data from Lab. You can see some datas from data sheet.
Other data should get from calculation using formulas.
Please get datas and do other questions.
Thankyou.
Part 3 1. Use the calipers to measure the diameter of the spherical flask. Record the result on your data sheet. Compute the radius and record the result on your data sheet. Fill the flask with water and mount it on the optical bench as demonstrated by the instructor. 2. Place the object lamp and the image plate on opposite sides of the flask, as shown in Figure 3. The object should be 15cm to 35cm from the flask. 3. Place the adjustable diaphragm between the object lamp and the flask, close to the flask. The smaller the hole in the diaphragm, the better-focused your image will be. 4. Adjust the position of the image plate until the image is sharp. Record the values of xo, xp, and xi (shown in Figure 3) on your data sheet, along with uncertainties. The uncertainty in n should be determined by how far you can move the image plate back and forth while maintaining a sharp image. 2R do XI xo XF Figure 3Explanation / Answer
1/f = 1/do + 1/di
Trial 1
do = 17.4 cm
di = 28.4 cm
=> 1/f = 1/17.4 + 1/28.4
=> f = 10.789 cm
Trial 2
do = 19 cm
di = 29.2 cm
=> 1/f = 1/19 + 1/29.2
=> f = 11.51 cm
Trial 3
do = 22 cm
di = 32.5 cm
=> 1/f = 1/22 + 1/32.5
=> f = 13.12 cm
Trial 4
do = 30 cm
di = 41.9 cm
=> 1/f = 1/30 + 1/41.9
=> f = 17.48 cm
=> fav = (10.789 + 11.51 + 13.12 + 17.48)/4
= 13.224 cm
