How do concave lenses affect light?

• They focus light to a single point.

• They spread light rays apart.

• They absorb light and create an image.

• They scatter light randomly.

How do convex lenses affect light?

• They absorb light and prevent it from passing through.

• They spread light rays apart.

• They bend light inward, focusing it to a point.

• They reflect light like a mirror.
