We can produce interference by two method: one, by division of amplitude and
second by division of wavefront. My book says that we divide wavefront and
amplitude in both the cases. I don't understand how. I've read Fresnel bi-prism,
Lloyd's mirror and parallel and wedge shaped film. But nothing explains what
does "division" actually means. And how the division takes place.
