a paraxial ray group of answer choices moves in a parabolic path. is a ray that moves nearly parallel to the optical axis. is a ray that moves exactly parallel to the optical axis. is a ray that has been reflected from parabolic mirror.

A paraxial ray group is a ray that moves nearly parallel to the optical axis.The paraxial rays stand in for the geometrical mechanics' tiny angle approximation, which is employed in Gaussian photonics and light beam mapping with an optics component like a lens. These rays are a group of rays that travel nearly parallel to the optical axis. The tangent and sine of every angle are assumed to be equal to the angles themselves when tracing.A paraxial ray is one that crosses the system's optical axis at a slight angle  (Ф) and stays near it throughout. The incident rays on the mirrors that are located extremely near the principal axis are what allow for three significant approximations in the calculation of the ray's path.Read more about paraxial rays on:https://brainly.com/question/1567014#SPJ4
