Question: Light of 600 nm wavelength illuminates a single slit. The intensity pattern shown is seen on a screen 2.0 m behind the slits. What is the width (in mm) of the slit?
The figure is an intensity vs x (cm) graph.
The x-axis goes from 0 to 1 to 2 to 3. (No values given on Intensity axis)
Between 0 and 1 there are two relative minima, between 1 and 2 there is one BIG Max, between 2 and 3 there are two relative minima.
