A measuring microscope is used to examine the interference pattern. It is found that the average distance between the centers of adjacent dark fringes is 0.450 mm. Taking into consideration the phase changes that take place upon reflection, which of the following is the condition for destructive interference of the reflected light? 2t = m + 1 2 λair, m = 0, 1, 2, ... 2t = mλair, m = 0, 1, 2, ...
