Intensity versus distance curve for a double slit diffraction experiment is shown in the figure below. If the width of each of the slits is $0.7 μ m$ , the separation between the two slits in micrometers is X, find the value of 100X ? (Specify your answer to two digits after the decimal point)

$Intensity versus distance for double slit diffraction$

Answer:

350

Solution:

Fringes in the central diffraction maximum: $\frac{2 d}{a} - 1 = 9$

$d = 5 a$

$d = 5 \times 0.7 = 3.5 μ m$

$X = 3.5$

$100 X = 350$
