Question
The figure shows the interference pattern obtained in double-slit experiment using light of wavelength 600 nm. P, Q, R, S and T are marked on five fringes .
Options
A.The third order bright fringe is R.
B.The third order bright fringe is T.
C.The fringe resulting from a phase difference of 4π is S.
D.If ᐃXA and ᐃXC represent path differences between waves interfering at P and R respectively then (|ᐃXC| - |ᐃ XA|) is equal to 300 nm.
