The Ionosphere reflects longer radio waves back to Earth. It varies in height going up at night giving the waves a long distance bounce.Flat vertical walls. Better refraction will Non-ferous metals. Horizontal plan will distort the image of the wave.\ CIV
Radio signals at a frequency below 30 mHZ can bounce off the ionosphere and be reflected back to earth. This is often referred to as DX skip. Sometimes, sunlight will excite the ions enough to where there'll form more dense spots within the ionosphere. These can, at times, allow higher frequency transmissions to use the same DX skip, although frequencies higher than 30 mHZ will normally pass right through it.
Radio signals at frequencies up to roughly 40 to 60 MHz are absorbed or reflected from the ionosphere. At higher frequencies, the signals easily penetrate the ionosphere and continue on into space. This is the reason that AM radio (1 MHz) and "short-wave" broadcasts (4-13 MHz) are often received from great distances, but TV (54 MHz and up) and FM radio (100 MHz) are not.

Atmospheric bounce is a technique used by Amateur Radio operators - to increase the distance their signals travel. Some frequency bands in use by amateur radio enthusiasts have a limit on the amount of power their equipment can produce. This often restricts the distance their signals can travel (sometimes to just a few miles). By using atmospheric bounce, an operator can 'reflect' the radio signal off the upper atmosphere (like shining a torch on a mirror) and thus the range can be (often dramatically) increased.
A moon bounce, also known as a bounce house or inflatable castle, is an inflatable structure often used for entertainment at children's parties or events. It provides a bouncy surface for kids to jump and play on in a safe and enclosed environment.
The titles are often omitted in the heading of a memo because the should be proper spacing in the paragraphs.
Radio waves are often referred to as space waves because they have the ability to move through space. Radio waves are a type of electromagnetic radiation.
When a person says their hair has no bounce, they are referring to their hair being flat. Persons with straight hair often complain of this as straight hair is often flat.
Yes, as often happens for both parties, there is a bounce after a convention. This refers to a boost in the candidate's poll numbers. The president definitely got a bounce after the Democratic convention.

It's a good practice to check the heading indicator against the magnetic compass at the start of each flight. Additionally, during the flight, you should cross-check the heading indicator with the magnetic compass at regular intervals, such as when turning onto a new heading or when experiencing unreliable heading indications.
