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.

The mirror formula, ( \frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i} ), is valid only for small apertures because it assumes paraxial rays (rays close to the optical axis). For large apertures, the non-paraxial rays behave differently and the simple mirror formula may not accurately predict the image location.
1 answer
A paraxial ray is one which makes a small angle to the optical axis of the system.

A convex mirror bulges out. A concave mirror curves inward.
For a convex mirror, light rays are reflected to meet at a point, while, for a concave mirror, light rays seem to be reflected from a point. If the incident rays were paraxial, the reflected rays are reflected to meet at, or appear to be reflected to a point referred to as the focal point of the lens. For a convex mirror, the focal point is real, while, that of a concave lens is virtual.

Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."

UV RAYS!!! The sun is the major natural source of UV Rays. UV Rays are invisable. They are still a form of light rays. UV stands for Ultra Violiet Rays. These (UV) rays cause sunburn and damage the eyes. Overexposure of UV Rays can cause serious skin cancer. UV Rays, however, can have useful effects, too. They can destroy harmful organisms.

Y-rays do exist. The Y is the Greek symbol for gamma. Gamma rays have more energy than x-rays and are therefore put after them.

Gamma rays are more penetrating than X-rays. This is because gamma rays have higher energy levels and shorter wavelengths, allowing them to penetrate deeper into materials.

A)B-rays are the only type of radioactivity that is electrically charged. Alpha (a-rays) and gamma (y-rays) rays are both uncharged, or neutral, particles. B-rays, or beta particles, are high-energy electrons that are emitted from the nucleus of an atom and are the only type of radioactivity that is electrically charged.
