Question

Two coherent light sources A and B are at a distance 22 from each other ( A = wavelength). The minimum distance from B on the x-axis at which the interference is destructive is

• A. \(\frac{3}{2} λ\)<
• B. \(\frac{λ}{2} \)
• C. \(\frac{15λ}{2} \)
• D. \(2\sqrt2λ\)

Answer 1

The Correct Option is C

The correct option is (C): \(\frac{15λ}{2} \)
