Question

Quizplus · Accepted Answer

The number of bright bands on each side of the central maximum is one less than the number of minima. Since the 4th minimum is at 35°, there are 3 bright bands on each side of the central maximum. Including the central maximum itself, there are 4 bright bands on each side.
