JEE Main 2005 Physics question
A Young's double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is
Answer: (3)
Solution
In Young's experiment with two long, narrow parallel slits, each slit acts as a line source; the locus of constant path difference on a screen parallel to the slits is a set of straight lines parallel to the slits, so
