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
- A⁻¹(0.01)
- B⁻¹(0.0001)
- C⁻¹(0.001)
- D⁻¹(0.1)
Correct answer
C. ⁻¹(0.001)
Step-by-step solution
In Young's double slit experiment half angular width is given by = d = 589 10⁻⁹ 0.589 10⁻³ =10⁻³ = ⁻¹(0.001)
