A double-slit experiment is performed using a helium-neon laser, with wavelength of 632.8 nm. The slit distance is 0.5 mm, and the distance to the screen is 1.8 m.
What is the width of the central bright fringe?
Homework Answers
width = lembda*distance between screen and slit/ distance between slit
width= 632.8*10^-9*1.8/0.5*10^-3
width = 0.00228 m
