A lens focuses light at a single point called the focal point.
An illustration of a vertical converging lens with 5 parallel rays coming from the left and hitting the lens. They all bend towards and through a point labeled focal point on the other side of the lens.
What is responsible for the light rays coming together at the focal point?
absorption
diffraction
reflection
refraction

Refraction.
The curved glass surfaces change the light’s speed and direction (Snell’s law), so each parallel ray is bent by a different amount and they meet at the focal point. (Reflection is what a mirror does; absorption removes light; diffraction is bending around edges and is not the primary cause here.)
