Q. In diffraction through a single slit, the angular width of the central maximum is

एकल झिरी के माध्यम से विवर्तन में, केंद्रीय अधिकतम की कोणीय चौड़ाई होती है

A
λ/a
λ/ए
B
2λ/a
2λ/ए
C
λ/2a
λ/2ए
D
a/λ
ए/λ

Explanation

The angular width (θ) of the central maximum in single-slit diffraction is:

Angular width=2λa\text{Angular width} = \frac{2\lambda}{a}

Where:

  • λ = wavelength of light

  • a = width of the slit
    This shows that narrower slits produce wider central maxima.
