introduce in light of wavelength 785 nm? Part (a):
What minimum path length difference is needed to introduce a phase shift of 170 in light of wavelength 568 nm?
Answer: 268.22 nm
Now I cant figure out part (b). :What phase shift will that path difference you calculated in part (a) introduce in light of wavelength 785 nm?
I got 116.17 degrees but thats wrong. Please help.
