Answer 1

for Plato users the awnser is refraction :)

Answer 2

The bending of light inside the lens of the eyepiece in a telescope refers to the phenomenon named "refraction." Refraction is the bending of light as it passes from one medium to another medium. For instance, when we place a pencil inside a glass of water, we see it bends because the light travels much slower in water than in air.
