What is the spacing d between the slits

Reference no: EM13540357

Light from a sodium light with wavelength 589 nm illuminates two narrow slits. The fringe spacing on a screen 180 cm from the slits is 5.00mm.

a) what is the spacing d between the slits ? (use millimeters)

b) What is the position on the screen of the brightest fringe, y4 ?

c) How much farther from one slit does the wave travel to this point than the wave from the from the other the slit ?

d) What wavelength of light would be needed so thatt the position in b) corresponds to y6 ?
