Find the thickness of a plate which will produce a change in optical path equal to half the wavelength λ of the light passing through it normally. the refractive index of the plate is μ,
- \(t=\frac{\lambda}{2(\mu-1)}\)
- \(t=\frac{\lambda}{(\mu-1)}\)
- \(t=\frac{2 \lambda}{(\mu-1)}\)
- \(t=\frac{\lambda}{2(\mu-1)}\)
Answer
(A) t= 2( -1)
