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 bends 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.
select the correct answer
in what manner does light enter a concave lens?
it travels in a straight line.
it spreads out or diverges.
it comes together or converges.

Explanation:

The text states that light enters the lens (medium) in a straight line. The diagram also shows parallel light rays entering the concave lens as straight lines before refraction and divergence.

Answer:

It travels in a straight line.
