Amplitude is the maximum displacement-I.e. the distance from the peak of the wave to its middle (generally zero) Frequency is the number of oscillations (complete wavelengt â¦ hs) per second.
Roof leaks can be hard to find, since they often run down the underside of sheathing or rafters to show up far from their actual source. The best time to try and find a leak is when itâs raining outside, or you can also mimic rain conditions by spraying water on the roof.Go in the attic and look for damp spots or water stains, trace them back to their highest point, then examine that part of the roof for any potential problems.he best time to try and find a leak is when itâs raining outside, or you can also mimic rain conditions by spraying water on the roof.

Most of the time, the leaks will only take a short time to repair, and best of all, you can do it on your own with some EPDM coating. This is a liquid coating that you apply to the roof after you clean it thoroughly. It goes on like paint, and most of the time, you will only need to apply a single coat.
