Question

If a glass slab is placed in the path of convergent light. The point of convergence
a)Shift towards the slab b) shifts away from the slab c) does not shift d) shift laterally.

Answer 1

b) shifts away from slab

Answer 2

Answer:

Option A is the correct answer

Shifts away from the slab

• The point of convergence or focus will move away from the glass slab if it is in the path of convergent light because, after passing through glass, the light will bend toward the normal and, as it emerges in the air, the light will converge out at a point distant from the glass slab.

Explanation:

• A glass slab is a material or sheet composed of glass that has three dimensions—length, breadth, and height—and is cuboidal in shape. It doesn't veer off course or scatter the light beams that are traveling through it.
• Thus, the incident and the emergent ray from the glass slab are parallel events. Only a lateral or (sideways) shift or displacement in the direction of light is created by the glass slab.
