What you are referring to is a "widow's walk", a place where one could watch for the return of a ship. A widow's peak is a hair term...the hairline descends to a point near the center of your forehead.

A Combined Services Drawing, or CSD, is used in construction. It is an illustration that provides a visual way to look at proposed development plans.

The inside of it is hollow. You cannot go inside of it. It is not open to the public. It is accessible only to workers doing maintenance on it. Check the video below showing when it was erected and you can see that there were workers inside it, helping to assemble it.

Buildings that do not conform to building regulations may not be structurally sound and may collapse, killing their occupants. Various aspects of construction, such as wiring, adequate availability of exits in case of fire, etc., can affect the safety of the building.

Resistance. And it doesn't "slow down current", it reduces the current.

You can turn a 12 x 12 foot (or inch) square into an octagon by measuring from the tip of each (90 degree) corner along the edge of each side 3 1/2 feet (or inches) to get the corners of your diagonal sides. You can also measure inward towards the center 2 1/2 feet (or inches, depending on the total desired size). Once you've drawn the sides, they should measure 5 feet (or inches) each.

1:Draw in the diagonals of the square. 2:Measure out from the centre of the square a distance of 6 ft along the diagonals towards each corner of the square and make marks. 3:You have 4 marks. Draw a line at right angles (90o) through each mark, to cut off the corners of the square. There's your octagon.

Red bends the least. If you look at a prism with a beam of light shining through it, you will see violet is bent the most. This due to the refractive index of the glass changing the wavelength.

Velocity & frequency are components of wavelength. So the refractive index is a ratio by which the speed of light is changed.

I am not sure if frequency is changed.
