Place the single slit wheel on the optics bench and turn the wheel to the variable slit width Slowly turn the wheel and observe what happens as the slit width increases.
What did you observe happen to the single-slit diffraction pattern as the slit width was increased?

Answer:

With the equation:

sin T = l / a (*)

note that the width of the central diffraction maximum is inversely proportional to the width of the slit. If we increase the width size, a, the angle T at which the intensity first becomes zero decreases, resulting bin a narrower central band.
