Answer:
= 1220 nm
= 1.22 μm
Explanation:
given data:
wavelength 
distance of screen from slits D = 3 m
1st order bright fringe is 4.84 mm
condition for 1 st bright is
---( 1)
and

= 0.0924 degrees
plug theta value in equation 1 we get


condition for 1 st dark fringe


= 2λ since from eq (1)
= 1220 nm
= 1.22 μm
Radiation is the only transfer in a vacuum
