Question
Whether the diffraction effects from a slit will be more clearly visible or less clearly, if the slit-width is increased?
✓

Answer

The width of the central band is inversely proportional to the slit Width. So, as the width of the slit is increased, the central band will become less wider and further bands will start merging in them. Hence, diffraction effects will be visible less clearly.
