A substance with a high index of refraction bends light more than a substance with a low index of refraction. It indicates that light travels more slowly in that substance compared to air or a vacuum. This property is used in optics for lenses and other optics applications.
Yes, rays that are parallel and close to the principal axis are known as paraxial rays. These rays are used in geometrical optics to simplify calculations and analyses of optical systems.
