\(S_{1}\) and \(S_{2}\) are the coherent point sources of light located in the \(x y\) -plane at points (0,0) and \((0,3 \lambda)\) respectively. Here \(\lambda\) is the wavelength of light. At which one of the following points (given as coordinates), the intensity of interference will be maximum?
- A \((3 \lambda, 0)\)
- B \((4 \lambda, 0)\)
- C \((5 \lambda / 4,0)\)
- D \((2 \lambda / 3,0)\)
Answer & Solution
Correct Answer
(B) \((4 \lambda, 0)\)
Step-by-step Solution
Detailed explanation
The given situation can be show as The intensity will be maximum at those given points where the path difference between the two interfering waves is an integral multiple of wavelength \(i . e ., \Delta x=n \lambda\) For the the given points, the intensily will be maximum for…
