The path difference between two interfering light waves meeting at point on the screen is $(\frac{87}{2}) λ$ . The band obtained at that point is

Options:

Answer:

Solution:

Path difference $= 87 (\frac{λ}{2})$ . $∴$ we get a dark point and $(2 n - 1) \frac{λ}{2} = 87 (\frac{λ}{2})$ $∴ 2 n = 88$ $∴ n = 44$ $∴$ we get $4 4^{th}$ dark band.
