Outrageously Funny Word Dictionary :: Outpupil

👉 The term "outpupil" in the context of optics refers to a phenomenon that occurs when an object is refracted through another medium, such as glass or water. This means that the light from the source enters the outpupil and is refracted back into its original direction. The result is called refraction, which can be either vertical (in the case of a spherical lens) or horizontal (in the case of a concave mirror).
