The size of the field 'decreases'. Imagine zooming in on your TV so that your face is pressed up against the screen. you can see the individual pixels but you cannot see the whole picture because the sizer of your 'field of view' has shrunk.
Answer: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.
