Answer:

Given that the 340 m/s and you have to find out the time period of the alarm siren? the distance between the two consecutive crests or troughs is lamda. Here lamda + lamda/4 = 1. Therefore, 5lamda/4 = 1, lamda = 4/5 = 0.8 m , T = 0.8/340 = 2.235 ms. Hope the student can get best answer on reading it and it is more helpful.
