Question

The vibrations of a string of length 60 cm fixed at both ends are represented by the equation y = 4 sin (( pi x)/(15)) cos ( 96 pi t) where x and y are in cm and t in second . ii. Where are the nodes located along the strings ? iii. What is the velocity of the particle at x = 7.5 cm at t = 0.25 s? iv. Write down the equations of component waves whose superposition gives the above waves .

Answer 1

Answer:

equation will be

A+sin(wt+theta)
