Explain Sampling at the Nyquist Rate?

What would happen if we reduced the sampling frequency? In the time domain, we would be getting less samples for each period. In the frequency domain, we would observe the multiple images of our signal centered at 0Fs, 1Fs, 2Fs, etc ... The lower the sample rate (Fs), the closer the images are to each other.

A limit is arrived while fs = 2fa, where an overlap occurs. The time domain picture looks similar our Case 2 plot, in which we are taking two samples per period.
