In a Young's double slit experiment, angula width of a fringe formed on a distant screen is 0.1°. If wavelength of light used is 6000 Å , then distance between the slits will be |
0.241 mm 0.344 mm 0.519 mm 0.413 mm |
0.344 mm |
$θ=\frac{λ}{d}$ or $d=\frac{λ}{θ}$ or $d=\frac{6×10^{-5}×180×7}{0.1×22}=0.344mm$ |
