A) 5
B) 4
C) 6
D) 7
E) 8

Question

Quizplus · Accepted Answer

The number of bright bands on each side of the central maximum is one less than the number of minima on that side. Since the 4th minimum occurs at 35°, there are 3 bright bands on each side of the central maximum, making a total of 4 bright bands including the central maximum.
