In young’s double slit interference experiment the distance between the two source 0.1/pie mm. The distance of the screen from the source is 25 cm. Wavelength of light used is 5000 A^o . Then what is the angular position of the first dark fringe is

If the entire arrangement is placed in a liquid of refractive index n In Young's double slit experiment the fringe width becomes the fringe width is β
