1. Gather a clean sheet of paper
2. Draw a solid mirror line appro. 10 cm long with its midpoint at center of paper, parallel to the long edge of the paper
3. make dot 5 cm from near side of midpoint of mirror line and label location as P
4. Secure paper to carboard with tape
5. Insert pin on dot labeled P
6. Measure the distance from pin to mirror line, dp, to 0.01cm. Label distance on paper and record measurement in data table 2
7. Place mirror on paper such that reflective side faces pin P and back side aligns with mirror line, ensuring mirror stand perpendicular to paper
8. Observe image of pin P in mirror from left side of pin, insert 2 pins aligned vertically with image
9. Remove 2 pins from last step and label pinholes as 1
10. Repeat steps 29-30 looking from the right side of the pin and label both pinholes as 2
11. Remove mirror and pin P from paper and set aside
12. Carefully remove paper from cardboard
13. Use ruler to draw a straight line that connects 1 to mirror line
14. Extend solid line past mirror line using dotted line at least 7 cm long
15. Use riler to draw line that connects 2 to mirror line
16. Extend solid line past mirror line using dotted line at least 7 cm long
17. Mark intersection with dotted lines and dot labeld as P
18. Measure distance from mirror line to O to 0.01 cm. Record distance on paper and in data table 2
19. Write name and date on paper, upload to photo2
