Question

unit exam - light
how does light enter a convex lens?
light diverges.
light curves.
light travels in a straight line.

Explanation:

A convex lens is a type of optical lens. When light enters a convex lens, it bends (refracts). This is because the lens has a curved surface. The refraction of light by the convex lens causes the light rays to converge (come together) at a focal point. Among the given options, "Light curves" is the most appropriate description as it refers to the bending (curving) of light due to refraction when entering the convex lens. "Light diverges" is incorrect as convex lenses converge light, not diverge. "Light travels in a straight line" is a general property of light in a uniform medium but does not specifically describe what happens when light enters a convex lens (where it bends due to refraction).

Answer:

Light curves.
