Write the relation between the path difference and wavelength of light wave used for constructive and destructive interference of light. |
|
Answer» a) For constructive interference ∴ Path difference = 2n\(\frac{\lambda}{2}\) = nλ Where λ → is wave length of light used n → 0, 1, 2, b) For destructive interference: ∴ Path difference = (2n + 1) Where λ → is wave length of light used n → 0, 1, 2,……… |
