For small angles (where sin 9 z 6', with 9 in radians), the distance between fringes is given by Ay : :cA/d (try prove this yourself). Calculate the distance between fringes for 677nm light falling on double slits separated by 0.0800 mm, located 2.71 m from a screen Image size: 5 M L Max Scum Jr 4 // a / y T /,/ in l" u-Ll/ I ~ Please enter a numerical answer below.

If it becomes dark when the path length difference is less than onefourth the wavelength, what is the thickest the oil can be and appear dark at all visible wavelengths? This particular type of oil has an index of refraction of 1.50, Take 375 nm to be the shortest visible wavelength in air Please enter a numerical answer below.
