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').
The cost to remove and dispose of an old vinyl 1 or PVC fence is $2-$5 per linear foot, which totals $400-$1000 for a standard 200 foot fence. Post caps are optional design details that are placed on top of each fence post 2 for a finished look.
