A beam of light is converging towards a point I on a screen. A plane glass plate whose thickness in the direction of the beam = t, refractive index = μ, is introduced in the path of the beam. The convergence point is shifted by
\[t\left( 1-\frac{1}{\mu} \right) away\]
\[t\left( 1+\frac{1}{\mu} \right) away\]
\[t\left( 1-\frac{1}{\mu} \right) nearer\]
\[t\left( 1+\frac{1}{\mu} \right) nearer\]
