Question

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

Answer 1

As you might know, the angle of refraction depends on the angle of incident. But I suspect that it would be closer than without the slab.

I also suspect the amount of 'more closeness' also depends on the thickness of the slab.

Without numbers it's always difficult to calculate it precisely.

Hope this helps.

Answer 2

the point of convergence light moves away from slab
