mark me as brainliest

Answer 2

Answer:

1. Glass slab

2. Refraction as a result of the glass slab

Explanation:

1. A glass slab is a narrow rectangular block of glass. When put on a surface, this glass slab seems to be lifted. This might be the entire glass from which he discovered the little fragment.

2. The raised appearance is caused by light refraction, which is the bending of light when it travels between two different mediums, where the light travels from the rarer to the denser medium, so the refracted ray is bent away from the normal with incident and refracted rays being parallel to each other. As a result, when we look through the glass slab, we see that the letter " A " is slightly higher.
