Respuesta :
Because they refract parallel light beams so that they collide, convex lenses are also known as converging lenses.
When parallel rays enter a convex lens, what happens?
A convex lens will cause a light beam that is parallel to the optical axis but not along it to shift course. In order to pass through the lens's focal point, which is located on the side opposite to the side from which light enters the lens, the direction of the light ray must change.
What takes place when parallel light beams strike a convex mirror?
Parallel light beams strike a convex mirror and reflect outward, moving away from a fictitious focal point (F). As each individual ray strikes that tiny area of the surface, it continues to reflect at the same angle.
