Question

a lens is a curved transparent material that refracts light. concave lenses curve inward to bend light in a process known as refraction. light enters the lens, also known as a medium, in a straight line. the lens slows the light down and refracts it. because the lens is thinner in the middle than it is on the edges, the light diverges, or spreads out, as it exits the lens.
what is the process of bending light called?
refraction
convergance
dissolution

Explanation:

The text on the left side of the image clearly states that concave lenses curve inward to bend light in a process known as refraction. This directly answers the question on the right side asking for the name of the process of bending light. Convergance and Dissolution are not related to the bending of light as described in the context.

Answer:

Refraction
