Question

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

• A. Moves away from slab
• B. Moves towards the slab
• C. Remains at the same point
• D. Undergoes lateral shift

Answer 1

Answer: (A)

Moves away from slab

If the glass slab is placed in the path of convergent light ,the point of convergence or focus will shift away from the glass slab as the light on passing through glass will bend towards the normal and after coming out in air, light will converge out at a point away from the glass slab.
