WebMay 5, 2010 · Refraction is defined as the act of determining the focal condition (emmetropia or various ametropias) of the eye and its corrections by optical devices, usually spectacles or contact lenses (Keeney, et al, 1995, p. 254). WebThe amount, or degree, of refraction is related to the difference between the speeds of light in the two materials of different densities—the greater the difference in densities, the more the speed changes, and the greater the bend.

WebAug 27, 2024 · Simply put, a refractor is a type of telescope that uses a lens to bend (or refract) light to a point. The point where the light path intersects is called the “focal point”, and is where your eyepiece, camera, or diagonal would go. The length from the lens to the focal point is known as the “focal length” of the telescope.
