Standing waves on the string are produced by oscillations having amplitude 0.005 m, angular frequency 942 rad/s and wave number of 0.750p rad/m.
i) Write down the equation of the standing wave?
ii) Determine at what distances from x = 0 are the nodes and antinodes?
iii) Determine the frequency of a point on the string at anti-node?
iv) When the string is 4m long, determine the number of nodes present?
