speed of wave (u)= 50cm/s
frequency (f)= 40hz
wavelength = w
speed = w×f
⇒ 50 = 40×w
⇒w = 50/40 = 1.25cm
Since minimum separation between consecutive compressions is equal to the wavelength of wave, answer is 1.25cm.

v = velocity of the wave = frequency * wavelength
wavelength = 50 cm /sec / 40 Hz = 1.25 cm
The separation between the consecutive compressions in the medium is called the wavelength. Hence, it is 1.25 cm.
