In Young's double slit experiment, the width of the fringes obtained with light of wavelength 6000 Å is 3.0 mm. If the entire apparatus is immersed in a liquid medium of refractive index 1.50, then the fringe width would be |
1.3 mm 2.0 mm 1.2 mm 1.5 mm |
2.0 mm |
The correct answer is Option (2) → 2.0 mm |
