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(.001)
- B⁻¹(.00001)
- C⁻¹(.0001)
- D⁻¹(.) 01
Correct answer
C. ⁻¹(.0001)
Step-by-step solution
In Young's double slit experiment half angular width is given by aligned &= d = 589 10⁻⁹ 0.589 10⁻³ =10⁻³ &= ⁻¹(0.001) aligned
