Question

fill in the blanks a glass slab is placed in the path of convergent light the point of convergence of light is ....

Answer 1

as we all know that when the light ray passes from denser to rarer or rarer to denser medium it gets refracted..

I this case the light rays are passing from the rarer medium (air) to denser medium (glass)
Thus the light rays will refract towards the normal.

so the answer will be
the blanks a glass slab is placed in the path of convergent light the point of convergence of light is ....slightly refracted and shifted


hope helped..
