Electromagnetic waves - radio waves - propagate through the air and vacuum by altering the electro-magnetic (EM) properties of space. They will be reflected whenever the EM properties of the space change. Incoming radiation from the sun partly ionizes some of the air molecules in the upper atmosphere and, for some frequencies, this will reflect (or refract) the EM signal.

This allows the EM signal to be reflected over long distances - even around the world - multiple hops. This effect is only true for HF radio - frequencies up to 10MHz or so. And varies naturally, day and night.

A related phenomenon affecting the upper atmosphere, is that incoming meteorites may give temporary ionization tracks. These have been used for burst transmissions but are not suitable for broadcast communications.

Higher frequencies, 100 MHz or so, use line - of - sight transmission, for these high frequencies are not affected by the ionized layers.

Efforts to promote sustainable practices such as extended producer responsibility and proper e-waste management aim to minimize the environmental impact of televisions throughout their life cycle.

I don't know about the show, but I had the album! it was a screenwriter named Sheldon Allman, who had a record called, I think, "Folk Songs for the 21st Century," that had the song "Do you have change for a hern/I beg you do not spurn/It may sound very funny/I just have martian money..." etc.

It was an album of offkey (not offcolor) songs with a science fiction theme. It was a classic, just sorry I gave it away somewhere along the way.

Slotted masses are used in physics experiments to create a known amount of mass that can be easily added or removed from a balance to measure the weight of an object or force due to gravity. They help in calibrating balances and studying the effects of different masses on physical systems.
