Answer 2

Answer:

Also, as the distance between the slits and the wall increased, the fringe width increased, because the light would have more space to diffract outwards, and thus be able to interfere more. ... Constructive interference results when a crest and another crest of different waves (or troughs) combine to create a larger wave.
