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.
The force between two infinite, parallel wires carrying current when placed close to each other is known as the magnetic force. This force is attractive or repulsive depending on the direction of the currents in the wires.
When two wires with parallel currents are placed close to each other, they can create a magnetic field that interacts with each other. This interaction can cause the wires to either attract or repel each other, depending on the direction of the currents. This phenomenon is known as the Ampre's force law.
When two measurements are close to each other, it is called precision. It indicates the level of consistency and repeatability in a set of measurements.
When sound particles are close together, it is called compression. This occurs during the peaks of a sound wave, where air molecules are densely packed together.
they are called the parallel bars
You would get into trouble. No school principal would allow you to get that close. It is illegal.

The 38th Parallel. Rather close to the South Korean city of Janggok
majority rules; now matter how close of a margin or the views of the opposition.
If the principal called 6 teacher and those teachers called 6 more teachers that would be 24 teacher in total. This is considered a math problem.
they dont come close enough to each other.
same similar, close, parallel, resembling, identical, corresponding, akin
It allows the driver to see how close they are to a vehicle or how close to the curb they are when they are parallel parking.
When you bring something close to boiling, it is called scalding it (or to "scald").
Friendship
No not on the principal amount. The funds that were used to purchased the CD originally had already been subject to income taxes.
