question: In a science class, the professor demonstrates refraction to the class. First, the professor shows a curved lens from a binocular, and then a flat pane of glass, demonstrating that
choices.text: the curved lens refracts more light the flat pane refracts more light.
choices.label: A B
para: The more curved the surface of a lens is, the more it refracts the light that passes through it.
