Standing waves on a string are generated by oscillations having amplitude 0.005 m, angular frequency 942 rad/s, and wave number 0.750p rad/m.a.) What is the equation of the standing wave?b.) At what distances from x=0 are the nodes and antinodes?b.) What is the frequency of a point on the string at an antinode?c.) If the string is 4m long, how many nodes are there?
