In young's double slit experiment angular width of fringes is \(0.20^{\circ}\) for sodium light of wavelength \(5890 \mathrm{~A}\). If the complete system is dipped in water, then the angular width of the fringe becomes
- \(0.11^{\circ}\)
- \(0.15^{\circ}\)
- \(0.22^{\circ}\)
- \(0.30^{\circ}\)
Answer
(B) 0.15^
