Answer 1

Answer:

zero

Explanation:

becose in parallel it will be zero

Answer 2

The power of parallel sided glass - slab is zero

Explanation:

We know that power of lens

P = 1/f

Where f is the focal length of the lens in m

In a parallel sided glass slab, if the rays are coming from infinity then they will not converge or appear to converge at any point as the emergent ray is parallel to the incident ray

Therefore, the focal length of the glass slab is at infinity

Therefore, the power of the parallel sided glass slab

P = 1/∞ = 0

Hope this answer is helpful.
