Diffraction

Question

What will be the angular width of central maxima in Fraunhofer diffraction when light of wavelength $6000 Å$ is used and slit width is $12 \times 10^{- 5} cm ?$

Easy

A

2 rad
B

3 rad
C

1 rad
D

8 rad

Solution

Angular width $= \frac{2 λ}{d} = \frac{2 \times 6000 \times 10^{- 10}}{12 \times 10^{- 5} \times 10^{- 2}} = 1 rad$
