Why did Young specifically perform a double-slit experiment to demonstrate the wave nature of light, since light will diffract and interfere even through a single slit? Is there something special demonstrated by the double-slit experiment that's not demonstrated by a single-slit experiment? (I'm specifically interested in the 19th century experiment...I understand the importance of the modern versions of the double-slit experiment.)
