Name ________________ Physics 198 Laboratory #2 Partner _______________ STANDING WAVES IN A STRING OBJECT: To study the relationship between tension, wavelength and frequency of a vibrating string. Ultimately you will determine the frequency of a small mechanical vibrator. (Those with absolute pitch might be able to guess the frequency!) Along the way you will encounter nodes, antinodes and traveling waves combining to for a standing wave on a string. EQUIPMENT: Vibrator with iron strip connected to string spanning tables. The other end of the string rides over a pulley and supports a mass that can be varied. Precision scales to measure weights and mass of the string as well as meter sticks are available. DESCRIPTION: An iron strip is made to oscillate by a small electromagnet driven by the oscillating current being supplied by our normal 120 volt AC (alternating current) power line. A string is connected to the tip of the iron strip so that oscillations of the iron cause transverse waves to travel down the string. For this to occur the string must be parallel to the iron strip. The tension
