Q. The width of the central maximum in single-slit diffraction is

एकल-स्लिट विवर्तन में केंद्रीय अधिकतम की चौड़ाई होती है

A
Directly proportional to slit width
स्लिट की चौड़ाई के सीधे आनुपातिक
B
Inversely proportional to slit width
स्लिट की चौड़ाई के व्युत्क्रमानुपाती
C
Independent of slit width
भट्ठा की चौड़ाई से स्वतंत्र
D
Zero
शून्य

Explanation

The angular width of the central maximum in single-slit diffraction is given by:

θ=λa\theta = \frac{\lambda}{a}

Where λ is the wavelength and a is the slit width. So, as slit width increases, the central maximum becomes narrower, and vice versa — hence, it is inversely proportional.
