A double slit experiment is immersed in water of refractive index 1.33. The slit separation is 1 ~mm , distance between slit and screen is 1.33 ~m The slits are illuminated by a light of wavelength 6300 Å . The fringe width is
Options
- A4.9 10⁻⁴ ~m
- B5.8 10⁻⁴ ~m
- C6.3 10⁻⁴ ~m
- D8.6 10⁻⁴ ~m
Correct answer
C. 6.3 10⁻⁴ ~m
Step-by-step solution
