YOUNG's experiment

JEE Mains 2015 Help › Optics questions › YOUNG's experiment

In a young's double slit exper. , light of wavelength 6000 AÂ° is used to produce fringes of width 0.8 mm at a distance of 2.5 m . If the whole apparatus is dipped in a liquid of refractive index 1.6 the fringe width will be

A) 0.2 mm B) 0.4 mm C) 0.6 mm D) 0.5 mm

B" = B/mew

=> B" = 0.8/1.6 = 1/2 mm =0.5 mm

If YDSE appartus is immersed in a liquid of refractive index u,then wavelength of light decreases .

It results in a decrease in width of fringes by Î¼ times
