Question:

A piece of transparent material having an index of refraction n is cut into the shape of a wedge as shown in figure. The angle of the wedge is small. Monochromatic light of wavelength λ is normally incident from above, and viewed from above. Let h represent the height of the wedge and ?? its width. Show that bright fringes occur at the positions x = λ?? (m + 1/2) 2hn and dark fringes occur at the positions x = λ?? m/2hn, where m = 0, 1, 2, . . . and x is measured asshown.
