a body vibrating with a time-period of 1/256s produces a sound wave which travels in air with a velocity of 350m/s. calculate the wavelength.

Velocity =350m/s
Time period = 1/256 s
frequency = 1/ (1 /256) =256Hz
​Velocity = wavelength × frequency
Wavelength = Velocity / frequency = 350/256 = 1·367
