Why do light waves with the same wavelength and constant phase difference interfere with eacher to produce light and dark interface patterns?
If their phase difference is constant, then they don't produce light and dark patterns. Light spots are produced where the two sources are in phase, and dark spots where they're out of phase.

Why center of newton ring is dark?
Newton's rings are created by the destructive and constructive interference between the light waves. Destructive is when one wave is at a crest (high point) and one is at a trough (low point) and they cancel each other out. Constructive is when both rays are at a crest or trough and they amplify each other. The dark areas (like the cenrte of the rings) are created by destructive interference.
How does a photocopier tell the difference between the light and dark areas of the original?
The original is lighted. The light reflects from the light areas and not from the dark areas. The reflected light shines on parts of a charged photoreceptor and removes the charge from those areas, but does not remove the charge from areas represented by the dark areas of the original. The charged parts of the photoreceptor attract the toner (dry ink), and the uncharged areas do not. Toner is then transferred from the photoreceptor to the paper and you get an image.
Why clouds are black and not white in rainy season?
The only difference between dark clouds and light clouds are they're thickness. A dark cloud is thikcer than a light cloud so it doesn't let as much light through. SO to answer your question, clouds are black in the rainy season because they are "holding" more water than they hold during the dry season

Why the transition phases of moon - from New Moon to Full Moon and vice versa except during half moon has Concave or Convex inner edges and not a flat inner edge?
The sunshine on the moon appears convex, straight (flat), or concave depending upon your vantage point. It is always the same porportion on the moon, but it looks differently because of the position of the Sun, Earth, and Moon at different times of the month. If you take a volleyball in a dark area, and shine a flashlight on the side of it, moving the ball and the light around will reproduce the moon phase effect, and give you a practical understanding of it.
