A beam of light of wavelength 600nm from a distance source falls on a single slit 1mm wide and a resulting diffraction pattern is observed on a screen 2m away. The distance between the first dark frings on either side of central bright fringe is

A

1.2cm

B

1.2mm

C

2.4cm

D

2.4mm

Text Solution

Verified by Experts

The correct Answer is:
d.
The distance between the first dark frigne on either side of the central bright fringe `=` width of central maximum `=(2Dlambda)/(a)`
`=(2xx2xx600xx10^(-9))/(10^(-3))=2.4xx10^(-3)m=2.4mm.`
(d) is the correct option.
