Answer:
The angle of deviation produced by a glass slab is 0 because the incident ray and emergent ray are parallel to each other.........

The deviation angle produced by the glass slab is 0⁰ and is parallel to the incident ray
Explanation :
when a light incidents on the one surface of the glass slab the light deviates due to the difference in refractive index it deviates towards the normal.
And when it emerges out from the other face it deviates away from the normal as the light travelling into rarer medium from denser medium.
In a glass slab as the both surfaces are parallel to each other, so does the emergent ray is parallel to incident ray.
