Question:medium
Angular width of the first minimum on either side of the central maximum due to a single slit of width \(a\), illuminated by a light of wavelength \(\lambda\) is
Angular width of the first minimum on either side of the central maximum due to a single slit of width \(a\), illuminated by a light of wavelength \(\lambda\) is
Show Hint
Single-slit central maximum extends from first minimum on one side to first minimum on the other side, so its angular width is doubled.
