Question
A thin slice cut out of a glass cylinder plane parallel to its axis. The slice is placed on a flat glass plate with the curved surface downwards. Monochromatic light is incident normally from the top. The observed interference fringes from the combination do not follow on of the following statements.
Options
A.The fringes are straight and parallel to the length of the piece.
B.The line of contact of the cylindrical glass piece and the glass plate appears dark
C.The fringes spacing increases as we go outwards.
D.The fringes are formed due to the interference of light reflected from the curved surface of the cylindrical piece and the top surface of the glass plate.
