there is no written rule that I am aware of, but common sense would indicate the bottom of the fixture should be at least 18" above the head of a 6ft tall person
That is correct, points are considered to be zero-dimensional in geometry, meaning they have no length, width, or depth. They are simply a position in space represented by coordinates.
After you measure the width of the door, you can use any unit of length you like to describe it. No unit is 'correct' or incorrect, but there's always one that produces the most convenient number ... the number that's easiest to write down, remember, and tell other people about. For the width of a door, I think inches would be a bit more convenient than feet.
The Milky Way spiral galaxy is about 100,000 light years in diameter, and about 3,000 light years thick at its center, and about 1,000 light years thick near its outer edge.
This is to maximize the effect of diffraction. The wavelength of the photon can be regarded as its 'size' . If it is too large then the slit is just to small for it and most of the photons will be absorbed or reflected. If it is far too small then the slit, in comparison, will be very large so most photons do not even notice its presence and will just continue on their merry way without interacting with it.
Voltage. A dimmer usaly chops the sine wave, leting it pass after a while.Another answerThe dimmer effectively becomes another device in the circuit. It effectively becomes a series circuit, therefore the voltage to the dimmed lights will be reduced in proportion with the relative position of the dimmer switch. HOWEVER...there is such a thing as "pulse width modulation" dimmers. They are typically used for devices that need full voltage but but you need to reduce output... such as fluorescent lights some fans and many other motors.Most dimmers are resistance type dimmers since the pulse width modulation dimmers are far more expensive.
The light fixture above a vanity mirror should ideally be about 75-80% of the width of the mirror to ensure even lighting on the face and minimize shadows. This proportion helps to distribute light evenly across the face for tasks like applying makeup or shaving. It's also important to consider the height at which the fixture is installed to prevent glare and provide adequate illumination.
When installing a large hanging light fixture in a room with high ceilings, consider using a sturdy ladder or scaffolding to reach the ceiling safely. Make sure to measure the height and width of the fixture to ensure it fits the space properly. It's also important to locate a ceiling joist or support beam to securely anchor the fixture. Additionally, having a second person to assist with holding the fixture in place while you make the necessary connections can be helpful.
The 2 light bath fixture being considered for the bathroom renovation project features a modern design with two lights, suitable for illuminating the bathroom space. It has a sleek finish and is designed to be mounted on the wall. The specifications include dimensions of 18 inches in width and 8 inches in height, with a brushed nickel finish. The fixture is compatible with standard light bulbs and can provide ample lighting for the bathroom area.
The standard height from the top of your table to the bottom of the light fixture above should be between 30"-36". Also the size of the fixture should be a little bit greater than 50% the width of the table itself.
The ratio of a round table to a pedestal base typically refers to their respective dimensions, particularly the diameter of the table to the height and width of the pedestal. While there isn't a standard ratio, a common guideline is that the diameter of the table should be about 2 to 2.5 times the diameter of the pedestal base to ensure stability and aesthetic balance. Ultimately, the specific ratio can vary based on design preferences and functional requirements.

There is no correct order. Give them in any order and, if relevant, state which one is which.
It's width to length ratio is 3 : 8.
