Given, θ=0.1 rad λ=6000 mathringA And we know that, θ=(λ/d). Where d= distance between slits d=(λ/θ)=(6000 × 10-10/ A -10)=6 × 10-6=6 μ m

Q. In YDSE angular fringe width is $0.1 r a d$ wavelength of light used is $6000 \overset{˚}{A}$ . Find distance between two slits.

$2 μ m$

$3 μ m$

$5 μ m$

$6 μ m$

Given, $θ = 0.1 r a d$
$λ = 6000 \overset{˚}{A}$
And we know that,
$θ = \frac{λ}{d}$ .
Where $d =$ distance between slits
$d = \frac{λ}{θ} = \frac{6000 \times 1 0 ^{- 10}}{A ^{- 10}} = 6 \times 1 0^{- 6} = 6 μ m$
