When are beats generated in two interfering waves? when they have slightly different velocities when they have the same wavelength when they have slightly different frequencies when they have the same amplitude when they have slightly different amplitudes

When they have slightly different frequencies.  This is because they will fall into and out of phase, leading to constructive and then destructive interference.  This change in interference causes a pulsating nature to the volume that is called beating
