Question
Part 2: Velocity of t e waves which form a standing wave on a string Procedure: 1) Use the double meter stick ck to measure the length of the sample piece of string. t sample, from the spool used in each string vibrator in the lab. msample, from the spool used in e 2) Use the digital mass bal ance to measure the mass of the sample piece of string, node at the 3) Ad just the vibrator's position so that the length of string, L, between the and the node at the vibrator is 100.0 cm. This distance will be kept consta ace a 100 gram mass on the end of the string to provide tension. for this part of lab. 4) PlExplanation / Answer
velocity of standing waves on a string : we take a fixed length of string of 100 cm and diffrent masses so as to change the tension in the string when we hang them from it .we genrate waves of desired frequency ( 100 HZ ) in the string and calibrate the standing waves produced to attain its maximum amplitude .now the number of half wavlengths is counted so as to get the wavlength of the wave . now the speed of the wave can be found using the formula speed = wavlength * frequency . the experiment is repeated for diffrent masses so as to establish a relationship between the variables.
