Solve the all parts of given question;
Question: Adjacent antinodes of a standing wave on a string are 15.0 cm apart. A particle at an antinodes oscillates in SHM with amplitude 0.850 cm and period 0.0750 s. The string lies along the +x axis and is fixed at x = 0.
Part A: Find the displacement of a point on the string as a function of position and time.
Part B: Find the speed of propagation of a transverse wave in the string.
Part C: Find the amplitude at a point 3.0 cm to the right of an antinodes.
I need help to find the speed of propagation of a transverse wave in the string.
