A beam of light is converging towards a certain point. A parallel sided glass plate is introduced in the path of the converging beam. How will the point of convergence be shifted ?

A beam of light is converging towards a point on a screen.A plane parallel plate of glass is introduced in the path of this converging beam.How will the point of convergence be shited ?Draw the ray diagram.

A beam of light is converging towards a point. A plane parallel plate of glass of thickness t, refractive index  is introduced in the path of the beam. The convergent point is shifted by (assume near normal incidence) :

A glass slab is placed in the path of a beam of convergent light. The point of convergence of light
