PhysicsEasysingle choice

The thickness of a plate having refractive index $μ$ which will produce a change in optical path equal to half the wavelength $λ$ of the light passing through it is

Options:

Answer:

Solution:

Let, $t =$ thickness of plate Given, optical path difference $= (μ - 1) t = λ /2$ $\Rightarrow t = \frac{λ}{2 ( μ - 1 )}$
