A transmission grating has $5000$ lines per cm. For $\lambda = 600\ \text{nm}$, the value of $\sin\theta$ for the first-order maximum is / एक पारगमन ग्रेटिंग में प्रति सेमी $5000$ रेखाएँ हैं। $\lambda = 600\ \text{nm}$ के लिए प्रथम कोटि उच्चिष्ठ हेतु $\sin\theta$ का मान है

$1.20$ / $1.20$
Correct Answer: $0.30$ / $0.30$
Grating spacing $d = 1/500000 = 2 \times 10^{-6}\ \text{m}$; from $d\sin\theta = \lambda$, $\sin\theta = 600 \times 10^{-9}/(2 \times 10^{-6}) = 0.30$. / ग्रेटिंग अंतराल $d = 1/500000 = 2 \times 10^{-6}\ \text{m}$; $d\sin\theta = \lambda$ से $\sin\theta = 600 \times 10^{-9}/(2 \times 10^{-6}) = 0.30$।
