पर्याय

• Zero

• 2π

• 4π

• 6π

Answer 1

In young 's double slit experiment, the phase difference between the light waves reaching third bright fringe from the central fringe will be 6π.

Explanation:

The phase difference between the light waves reaching the third bright fringe from the central bright fringe will be Δ Φ = 2 × 3 × π = 6π  (case of constructive interference)
