Part D

Are the $$ values in part B precisely halfway between the $$ values for adjacent minima?

From part $B,$ the first maximum is at $=4\mathrm{.}49$rad, while midway between the first and second minima is $=4\mathrm{.}49$rad, so this maximum is midway between the adjacent minima. The second maximum is at $=7\mathrm{.}73$rad, while midway between the second and third minima is $=7\mathrm{.}85$rad, so the second maximum is not midway between the adjacent minima.

From part $B,$ the first maximum is at $=4\mathrm{.}49$rad, while midway between the first and second minima is $=4\mathrm{.}49$rad, so this maximum is midway between the adjacent minima The second maximum is at $=7\mathrm{.}73$ rad, while midway between the second and third minima is $=7\mathrm{.}73$rad so the second maximum is midway between the adjacent minima.

From part $B,$ the first maximum is at $=4\mathrm{.}49$rad, while midway between the first and second minima is $=4\mathrm{.}71$rad, so this maximum is not midway between the adjacent minima. The second maximum is at $=7\mathrm{.}73$ rad, while midway between the second and third minima is $=7\mathrm{.}73$rad, so the second maximum is midway between the adjacent minima.
