Product description
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 whose plane is approximately perpendicular to the direction of their propagation. By writing the equations of both plane waves and adding their fields, show that the distance Dx between two adjacent interference fringes on the screen is determined by the expression Dx = l/j.
