A string of length 0.4 m and mass 10 ^(-2) kg is tightly clamped at its ends. The tension in the string is 1. 6 N. identical wave pulses are produced at one end at equal intervals of time Delta t . The value of Delta t which allows construction interference between successive pulses is

A string of length 0.4 m and mass 10^(-2) kg is clamped at one end . The tension in the string is 1.6 N . The identical wave pulses are generated at the free end after regular interval of time , Delta t . The minimum value of Delta t , so that a constructive interference takes place between successive pulses is
