A converging lens forms a real image I of an object on its principle axis. A rectangular glass slab of refractive index μ and thickness x is introduced between I and lens. Image I will move:

Towards the lens by \(\left( {1 - \frac{1}{\mu }} \right)x\)

Away from the lens by (μ – 1) x

Away from the lens by \(\left( {1 - \frac{1}{\mu }} \right)x\)

Towards the lens by (μ – 1) x
