Answer the following question.
State the assumptions on which ray optics is based.
Ray optics is based on the following assumptions:
- Objects and images are situated close to the principal axis.
- Rays diverging from the objects are confined to a cone of a very small angle.
- If there is a parallel beam of rays, it is paraxial, i.e., parallel and close to the principal axis.
