In Young's double slit experiment with sodium vapour lamp of wavelength 589 nm and the slits 0.589 mm apart, the half angular width of the central maximum is

Options:

Answer:

Solution:

In Young's double slit experiment half angular width is given by $sin θ = \frac{λ}{d}$ $= \frac{589 \times 1 0 ^{- 9}}{0.589 \times 1 0 ^{- 3}} = 1 0^{- 3}$ $\Rightarrow θ = sin^{- 1} (0.001)$
