In the Young's double slit experiment the intensity produced by each one of the individual slits is I₀ . The distance between two slits is 2 mm. The distance of screen from slits is 10 m. The wavelength of light is 6000 ~A ^ . The intensity of light on the screen in front of one of the slits is _ _ _ _ .

- B2 I_ o
- C4 I_ o
- DI_ o
Correct answer
D. I_ o
Step-by-step solution
In Young's double slit experiment: d = 2 mm, D = 10 m, = 6000 Å The point in front of one slit is at y = d 2 from the central axis. I = 4I₀ ^2 ( d y D ) = 4I₀ ^2 ( 2 10⁻³ 1 10⁻³ 6000 10⁻¹⁰ 10 ) = 4I₀ ^2 ( 3 ) = 4I₀ 1 4 = I₀
