what is the answer to this question from this years aieee(may 1st) paper physics?A thin air film is formed by putting the convex surface of a plane convex lens over a plane glass plate.with monochromatic light,this film gives an interference pattern due to reflected light from the top(convex) surface and the bottom(glass) surface of the film. statement 1-when light reflects from the air glass plate interface,the reflected wave suffers a phase change of pi. statement 2-the centre of the interference pattern is dark. pls explain .
