Consider two diffraction gratings with the same slitseparation,the only difference being that one grating has 3 slitsand theother 4 slits. If both gratings are illuminated with a beamof thesame monochromatic light, make a statement concerningtheseparation between the orders.
Answer
Both gratings produce the same separation between orders, buttheorders are better defined with the 4-slit grating.
The grating with 3 slits produces the greater separationbetweenorders.
Both gratings produce the same separation between orders.
The grating with 4 slits produces the greater separationbetweenorders.
