Suppose you have two coherent microwave beams, one beam at 45 degrees to a reflecting wall and the other one at 90 degrees, with the two beams pointing to the same point on the wall.
If the two beams are 180 degrees out of phase and destructively interfere at the point on the wall, will the 45 degree beam still reflect off the surface, in the same manner it will when you turn off the 90 degree beam, i.e., when there is no destructive interference?
