NEET · Physics · STD 12 - 10. Wave optics
Two coherent sources of light interfere and produce fringe pattern on a screen. For central maximum, the phase difference between the two waves will be,
- A \(\frac {\pi}{2}\)
- B \(0\)
- C \(\pi\)
- D \(\frac {3\pi}{2}\)
Answer & Solution
Correct Answer
(B) \(0\)
Step-by-step Solution
Detailed explanation
For central maximum, path difference is zero hence phase difference for coherent sources of light will be zero. \(\because 0=\frac{2 \pi}{\lambda} \Delta x\)
