Çözüldü Young's Double-Slit Experiment - Exponential Numbers - Conversion Between Length Units in SI

In Young's Double-Slit Experiment, the identical slits are 0.7 mm apart, and the pattern is observed on a screen at a distance of 1 meter from the plane of the slits. If the distance between the 10th dark fringe and the central bright fringe is 9.5 mm, what is the wavelength of the light used in the arrangement?

A) 7 A°
B) 7 mm
C) 7·10^(-9) m
D) 0.7 µ
E) 7·10^(-6) cm

7·10^(-2)·0.95 / 100 = (10 - 1 / 2)·λ ⇒ λ = 7·10^(-5) cm = 0.7 µ.
