Find the angular fringe width in a Young’s double slits experiment with blue-green light of wavelength 6000 Å. The separation between the slits is 3.0 × 10 –3 m.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
× 2 × 10 –4 degree = 0.011º
Sol. As λ << d; ⇒ we can use
β = 
so 
= 
= 2 × 10 –4 radian
= 
× 2 × 10 –4 degree = 0.011º
