Question

The phase difference between the two superimposing waves that give rise to a bright spot in a Young’s double-slit experiment is (\(n\) is an integer) :

• A. \(2n\pi\)
• B. \(2n\pi + \frac{\pi}{4}\)
• C. \(2n\pi + \frac{\pi}{2}\)
• D. \(2n\pi + \pi\)

Hint:

Remember the simple rules for interference: - Bright spot (Constructive): Phase difference \(\phi = 2n\pi\); Path difference \(\Delta x = n\lambda\). - Dark spot (Destructive): Phase difference \(\phi = (2n+1)\pi\); Path difference \(\Delta x = (2n+1)\frac{\lambda}{2}\).
