Lesson Summary. Infrared waves are just part of the electromagnetic spectrum; to be exact, they're waves that have a wavelength between 700 nm (nanometers) and 1 mm. This can't quite be detected by human eyes-it is just beyond the red side of the rainbow.esson Summary.

Also called split rail or post and rail, a ranch-style vinyl fence with two to four rails typically costs do-it-yourselfers $4-$12 a linear foot for materials; with a gate and other options do-it-yourself materials can total $500-$1,400 for 100' of fencing and $3,500-$10,000 to enclose a simple square acre (about 830').
An average pricing for railing will run around $300.00 for the first rail and $150.00 per rail connected to it. These prices usually include installing balusters, rosettes, and Newels. Installing a monkey tail, a valute, an upease or pin top newels will usually go up in price a little at about 10%-20% increase.
