A double slit is illuminated by light of wavelength 6000 Å. The slits are 0.1 cm apart and the screen is placed one metre away. calculate :
sepration between the two adjacent minima

Explanation

Separation between two adjacent minima = fringe width `beta`
`beta=(lamdaD)/d=(6times10^-7times1)/(1times10^-3)=6times10^-4m=0.6mm`
