The lens in the eyepiece of a telescope magnifies light by bending it. What is this bending called?

dispersion

radiation

reflection

refraction

absorption

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.
