In Young's double-slit experiment with $\lambda = 550\ \text{nm}$, $D = 2.0\ \text{m}$ and $d = 1.0\ \text{mm}$, the distance of the third bright fringe from the central maximum is / $\lambda = 550\ \text{nm}$, $D = 2.0\ \text{m}$ तथा $d = 1.0\ \text{mm}$ वाले यंग प्रयोग में केंद्रीय उच्चिष्ठ से तृतीय दीप्त फ्रिंज की दूरी है
1.
$1.1\ \text{mm}$ / $1.1\ \text{mm}$
2.
$3.3\ \text{mm}$ / $3.3\ \text{mm}$
3.
$2.2\ \text{mm}$ / $2.2\ \text{mm}$
4.
$4.4\ \text{mm}$ / $4.4\ \text{mm}$
Correct Answer: $3.3\ \text{mm}$ / $3.3\ \text{mm}$
$y_3 = 3\beta = 3\lambda D/d = 3 \times 550 \times 10^{-9} \times 2.0/10^{-3} = 3.3 \times 10^{-3}\ \text{m} = 3.3\ \text{mm}$. / $y_3 = 3\beta = 3\lambda D/d = 3 \times 550 \times 10^{-9} \times 2.0/10^{-3} = 3.3 \times 10^{-3}\ \text{m} = 3.3\ \text{mm}$।
