In Young's Double Slit Experiment, the source slit is moved closer to the plane of the two slits. Which of the following changes will be observed? A) The fringe width remains unchanged. B) The interference pattern disappears if the source slit is brought too close (violating the Fresnel distance condition). C) The intensity of the fringes increases. D) The angular width of the fringes decreases.

A single problem often links mechanics with electrostatics, or calculus with coordinate geometry. In Young's Double Slit Experiment, the source slit
