Chapter 35.3, Problem 35.3TYU

A two-slit interference experiment uses coherent light of wavelength 5.00 × 10⁻⁷ m. Rank the following points in the interference pattern according to the intensity at each point, from highest to lowest. (i) A point that is closer to one slit than the other by 4.00 × 10⁻⁷ m; (ii) a point where the light waves received from the two slits are out of phase by 4.00 rad; (iii) a point that is closer to one slit than the other by 7.50 × 10⁻⁷ m; (iv) a point where the light waves received by the two slits are out of phase by 2.00 rad.
