How will the expression for Dх change in the previous problem (The directions of propagation of two plane waves of the same length l make a small angle j with each other. The waves fall on a screen, the plane of which is approximately perpendicular to the direction of their propagation. By writing the equations of both plane waves and adding them fields, show that the distance Dх between two adjacent interference fringes on the screen is determined by the expression Dх = l/j.), if the interfering rays fall obliquely on the screen?
