A Youngâs double slit apparatus has the slit separation of
0.15mm and the distance between the slits and the viewing
screen is 150 cm.
A) If monochromatic light of wavelength ? = 550x10-9 m passes
through the slits, calculate the distance between the central
(bright) fringe and the adjacent bright fringe.
B) Now imagine that you are using X-rays, ?=1x10â9 m insteadof
visible light in this experiment. What would the slitseparation
need to be in order to have the distance between these firsttwo
bright fringes be 1cm?
