A string vibrate according to the equation `y = 5 sin ((pi x)/(3)) cos (40 pi t)` where x and y in cm's and t is in second.
(i) What is the equation of incident and reflected wave ?
(ii) What is the distance between the adjacent nodes ?
(iii) What is the velocity of the particle of the string at the position x = 1.5 cm when `t = (9)/(8) sec` ?

A string vibrates according to the equation y=5 sin ((2 pi x)/(3)) cos 20 pi t , where x and y are in cm and t in sec . The distance between two adjacent nodes is

A stationary wave is given by y = 5 sin (pi x)/( 3) cos 40 pi t where x and y are in cm and t is in second. a. What are the amplitude and velocity of the component wave whose superposition can give rise to this vibration ? b. What is the distance between the nodes ? c. What is the velocity of a particle of the string at the position x = 1.5 cm when t = 9//8 s ?
