Two slits in Young's double slit experiment are 1.5 mm apart and the screen is placed at a distance of 1 m from the slits. If the wavelength of light used is 600 10⁻⁹ ~m then the fringe separation is
Options
- A4 10⁻⁵ ~m
- B9 10⁻⁸ ~m
- C4 10⁻⁷ ~m
- D4 10⁻⁴ ~m
Correct answer
D. 4 10⁻⁴ ~m
Step-by-step solution
Fringe width = Fringe separation ( )= D d = 600 10⁻⁹ 1 1.5 10⁻³ = 6 10⁻⁷ 1.5 10⁻³ =4 10⁻⁴ ~m
