a student performs a standard two - slit interference experiment. a light sensor is used to measure the intensity of the light along the screen and plot of intensity versus position measured from the center of the pattern is plotted. A ) select all of the positions listed where interference is maximally constructive. 

B ) Select all of the positions listed where interference is maximally destructive. 

C ) Select all of the positions listed where there is no path difference from the two slits.

 D ) Select all of the positions listed where the path difference from the two slits is four full wavelengths. 

E ) Select all of the positions listed where the path difference from the two slits is 5 / 2 ( two and one - half wavelengths ) .
