एक विवर्तन जाली में समान अंतर पर संकीर्ण छिद्रों या रेखाओं की एक बड़ी संख्या (n) शामिल होती है।
d sin θ = mλ
गणना:
दिया गया है:
माना कि 3 cm चौड़े विवर्तन जाली पर n रेखाएं हैं।
d = 3/n cm = 30/n mm
λ = 600 nm = 600 × 10-9 m, d = 3 cm = 30 mm,
d sin θ = mλ
\(\frac{{30}}{n} \times \sin 30^\circ = 2 \times 600 \times {10^{ - 6}}\)
n = 12500Last updated on May 26, 2025
