Question
The next three questions refer to the graph of light intensity vs. position of the probe shown below. The graph was made with a laser pointer (650 nm) shined through two very narrow slits separated by a small distance. The slits were 3 meters away from the probe.
What is the separation of the slits in millimeters?
Answer: 0.585mm
What is the width of the slits in millimeters?
(P.S. I just need the answer to what is the width please??? Thank you!)

2-slit diffraction 400 r 300 200 100 -40 -30 20 100 10 20 3040 position [mm]Explanation / Answer
For slit separation,
d = D lambda / y = 3m*650 nm/3.333mm = 0.585 mm
for slit width
b = D lambda / large y = 3m*650nm /20mm = 0.0975 mm
