Разность между двумя этими расстояниями: 10 см
Сколько длин волн укладывается на этой разности?
10см/ 1.5 мкм = 100000 / 1.5 = 66666.6 длин волн. Это число больше похоже на полуцелое, чем на целое (ближе к 66666.5, чем к 66667), поэтому ответ: скорее минимальна, но вообще ни максимальна и ни минимальна.
