JEE Main 2022 Physics question

Using Young's double slit experiment, a monochromatic light of wavelength 5000 Å produces fringes of fringe width 0.5 mm. If another monochromatic light of wavelength 6000 Å is used and the separation between the slits is doubled, then the new fringe width will be :

• (1)0.5 mm
• (2)1.0 mm
• (3)0.6 mm
• (4)0.3 mmCorrect
