Question

Light from a sodium lamp (λ=589nm) illuminates two narrow slits. The fringe spacing on a screen 160 cm behind the slits is 4.4 mm .

What is the spacing (in mm) between the two slits?

Answer 1

Answer #1

d=589 nm = 589 810 m. D = 160cm. -1.6om I= 4.4mm = 4.4 X 103 m Spacing between y= AL the two slits (d) d = XL y - 589 8109 X1
