Time period = 1/256s
We know,
Velocity = frequency × wavelength
We need to find frequency:
Time period is reciprocal of frequency..
∴Frequency = \frac{1}{ \frac{1}{256 } }25611
= 256 Hz
So, Velocity = frequency × wavelength
Then, wavelength = \frac{velocity}{frequency}frequencyvelocity
= \frac{350}{256}256350
= 1.367 m

Given Time period = 1/250 sec.
We know that Frequency = 1/Time period
= 1/1/250
= 250 HZ
Given Velocity = 350m/s,
We know that Velocity = Wavelength * Frequency
350 = Wavelength * 250
Wavelength = 350/250
= 1.4 m.
Therefore the wavelength of the sound wave = 1.4m.
Hope this helps!
