Hi,
It´s a common question in scientific message boards: "Does destructive interference violate the law of conservation of energy?"
The standard answer is no. There´s no way to realize complete destructive interference. It´s always accompanied by constructive interference.
Let us now assume the following:
Light is transmitted tangential in an appropriate distance to a black hole, so that it travels around it. (see picture http://www.geocities.com/cyberflair/black_hole1.jpg ). Then another light beam is transmitted, so that it´s phase shift is lambda/2 if it reaches the first light beam. Will this result in a completely destructive interference?
