Hi, i need help with part ii of this question. It gives you the speed of sound. but asks you for minimum separation of particles. So I guess path difference? but how would you work that out. It is pi degrees out of phase but what is lamba?

You can work out wavelength because you've been told the speed and the frequency

180° out of phase = half the wavelength

Lambda (λ) , is the wavelength
