An interference pattern is formed on a screen by shining a planar wave on a double-slit arrangement (left). If we cover one slit with a glass plate (right), the phases of the two emerging waves will be different because the wavelength is shorter in glass than in air. If the phase difference is 180 degrees how is the interference pattern, shown left, altered?

Ans: Bright and Dark fringes are interchanged. WHY??
