Unformatted text preview: 34th International Physics Olympiad TAIPEI, TAIWAN Experimental Competition Wednesday, August 6, 2003 Time Available : 5 hours Read This First: 1. Use only the pen provided. 2. Use only the front side of the answer sheets and paper. 3. In your answers please use as little text as possible; express yourself primarily in equations, numbers and figures. If the required result is a numerical number, underline your final result with a wavy line . 4. Write on the blank sheets of paper the results of your measurements and whatever else you consider is required for the solution of the question and that you wish to be marked. 5. It is absolutely essential that you enter in the boxes at the top of each sheet of paper used your Country and your student number [ Student No. ] . In addition, on the blank sheets of paper used for each question, you should enter the question number [ Question No. : e.g. A-(1) ], the progressive number of each sheet [ Page No. ] and the total number of blank sheets that you have used and wish to be marked for each question [ Total No. of pages ] . If you use some blank sheets of paper for notes that you do not wish to be marked, put a large cross through the whole sheet and do not include them in your numbering. 6. At the end of the exam please put your answer sheets and graphs in order. 7. Error bars on graphs are only needed in part A of the experiment. 8. Caution: Do not look directly into the laser beam. You can damage your eyes!! Apparatuses and materials 1. Available apparatuses and materials are listed in the following table: Apparatus & material Quantity Apparatus & material Quantity A Photodetector (PD) 1 I Batteries 2 B Polarizers with Rotary mount 2 J Battery box 1 C 90 TN-LC cell (yellow wires) with rotary LC mount 1 K Optical bench 1 D Function generator 1 L Partially transparent papers 2 E Laser diode (LD) 1 M Ruler 1 F Multimeters 2 N White tape * (for marking on apparatus) 1 G Parallel LC cell (orange wires) 1 O Scissors 1 H Variable resistor 1 P Graph papers 10 * Do not mark directly on apparatus. When needed, stick a piece of the white tape on the parts and mark on the white tape. 2. Instructions for the multimeter: A B B H F F C D E I K J ON OFF HI LO ‧ “DC/AC” switch for selecting DC or AC measurement. Use the “V ‧ Ω ” and the “COM” inlets for voltage and resistance measurements. Use the “mA” and the “COM” inlets for small current measurements. The display ‧ then shows the current in milliamperes. Use the function dial to select the proper function and measuring range. “V” is for ‧ voltage measurement, “A” is for current measurement and “ Ω ”is for resistance measurement....
