Q.

In a single slit experiment, a parallel beam of green light of wavelength 550 nm passes through a slit of width 0.20 nm. The transmitted light is collected on a screen 100 cm away. The distance of first order minima from the central maximum will be x×10-5m. The value of x is _____.         [2024]


Ans.

(275)

λ=550 nm

D=100 cm

a=0.20 mm

y=Dλa=100×10-2×550×10-90.2×10-3=275
