17. Interference maxima occur at angles θ such that d sin θ = ,where m is an integer. Since d =2 . 0m and λ =0 . 50 m, this means that sin θ =0 . 25 m . We want all values of m (positive and negative) for which | 0 . 25 m |≤ 1. These are 4, 3, 2, 1, 0, +1, +2, +3, and +4. For each of these except 4and
