In a certain double slit experimental arrangement interference fringes of width `1.0mm` each are observed when light of wavelength `5000Å` is used. Keeping the set up unaltered, if the source is replaced by another source of wavelength `6000Å`, the fringe width will be

A

0.5 mm

B

1.0 mm

C

1.2 mm

D

1.5 mm

Text Solution

Verified by Experts

The correct Answer is:
C
`beta prop lambda implies (beta_(1))/(beta_(2))= (lambda_(1))/(lambda_(2)) implies (1)/(beta_(2))= (5000)/(6000) implies beta_(2)= 1.2 mm`
