What will be the angular width of central maxima in Fraunhoffer diffraction when light of wavelength

6000\mathop \mathrm{A}\limits^ \circ

is used and slit width is

12 \times {10^{ - 5}}\;cm

View answer and explanation

Correct option: C

1\;rad

Option C (

1\\;rad

) is correct because the angular width of the central maxima in Fraunhofer diffraction is given by

2\theta = \frac{2\lambda}{d}

.
