1. The problem statement, all variables and given/known data The wave function for a certain standing wave on a string that is fixed at both ends is given by y(x, t) = (5.00 cm) sin (2.50 m^(− 1)x) cos (500 s^(− 1)t) A standing wave can be considered as the superposition of two traveling waves. 1. a. Give the speed in m/s rounded to a whole number. b. Give the amplitude in cm rounded to one decimal place 2. What is the distance between successive nodes on the string? Give your answer in m rounded to two decimal places. 3. What is the shortest possible length of the string? Give your answer in m rounded to two decimal places. 2. Relevant equations 3. The attempt at a solution I got all the answers: 1a. 200m/s 1b. 5.0 cm 2. 1.26 m 3. 1.26 m But I am sure about none of them, please check if right or not? If it's not, then please help me out. Thanks !
