Answer :

GinnyAnswer

Final answer:

In single-slit diffraction, widening the slit makes the central band wider, not thinner.


Explanation:

False. In single-slit diffraction, as the width of the slit is increased, the central band actually gets wider, not thinner. This is because a wider slit allows more light to diffract, resulting in a broader central band.
