Amonochromatic beam of light is sent through each of the following six optical slides.
rank these scenarios on the basis of the angle of the first interference maximum.
rank from largest to smallest. to rank items as equivalent, overlap them.

a. difraction grating with 1000 lines/cm
b. single slit slide with width .04mm
c. single slit slide with width .01mm
d. double slit slide with spacing .08mm
e. diffraction grating with 500 lines/cm
f. double slit slide with spacing .02mm
