In Young's double slit experiment, the spacing between the slits is d and wavelength of light used is 6000 A ˚ . If the angular width of a fringe formed on a distance screen is 1 ∘ , then value of d . is

Here, sin θ = ( D Y ) ∴ Δ θ = D Δ Y Angular fringe width θ 0 = Δ θ (width Δ Y = β ) θ 0 = 1 ∘ = 180 π rad and λ = 6 × 1 0 − 7 m d = θ 0 λ = π 180 × 6 × 1 0 − 7 = 0.03 mm

In Young's double slit experiment, the spacing between the slits is $d$ and wavelength of light used is $6000 \overset{˚}{A}$ . If the angular width of a fringe formed on a distance screen is $1^{\circ}$ , then value of $d$ . is

Options:

Answer:

Solution:

Here, $sin θ = (\frac{Y}{D}) ∴ Δ θ = \frac{Δ Y}{D}$ Angular fringe width $θ_{0} = Δ θ$ $(width Δ Y = β)$ $θ_{0} = 1^{\circ} = \frac{π}{180} rad and λ = 6 \times 1 0^{- 7} m d = \frac{λ}{θ _{0}} = \frac{180}{π} \times 6 \times 1 0^{- 7} = 0.03 mm$
