Question

In a single slit experiment, the width of the slit is doubled. Which one of the following statements is correct?

• A. The intensity and width of the central maximum are unaffected.
• B. The intensity and angular width both are doubled.
• C. The intensity increases by a factor 4 and the angular width decreases by a factor of $\frac{1}{2}$.
• D.

Hint:

Logic Tip: A wider slit results in a narrower and much brighter central diffraction peak.
