Q- The vibrations of a string of length 60 cm fixed at both ends are represented by the equation
y = 4sin (π x/15) cos(96 π t)
(here x and y are in cm and t in seconds)
(a) What is the maximum displacement of a point at x = 5 cm?
(b) Where are the nodes located along the string ?
(c) What is the velocity of the particle at x = 7.5 cm and at t = 0.25 s?
(d) Write down the equations of the component waves whose superposition’s give the above wave.
