Fringes in the Thomas Young experiment are produced using sodium light of wavelength 670 nm and two slits which are 1.2 mm apart. If the fringes are formed on a screen 0.8 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).
In Biprism experiment the fringe width
is 0.30 mm. If slits are covered by glass plate of
thickness 0.04 mm and refractive index µ = 1.5,
then the fringe width is
