yes, they are also a type of electromagnetic waves. any EM wave can travel in space as they can pass through vacuum.
By use of electromagnetic waves, usually microwaves or radio waves.
yes
Microwaves need electricity to run, but this is easily produced from solar panels. Campers and caravaners with solar panels and batteries have 12 volt microwaves that run successfully.
Gamma rays
They are made of metal for the simple reason of just not many things can survive in space due to the fact space is cold and they is no air. Anything else may just detoryed by metors or any other space junk hitting them. That's Really it. Metals reflect microwaves that carry information between communication satellites and satellite dishes. Other materials tend to absorb the information so it doesn't travel efficiently.
no, because microwaves do not take up space
The background radiation from the big bang
Because it takes up space, and anythign that has mass in it is matter.
By use of electromagnetic waves, usually microwaves or radio waves.
Some advantages to owning a small microwave are: They are cheaper than regular microwaves, they take up less space, will require less electricity to function.
Radio telescopes have beamed messages destined to be picked up by other civilisations. The programme ,SETI is ongoing and the Aricibo Dish in Puerto Rico was used for this purpose. The NASA deep space network used microwaves to communicate with the Apollo astronauts and do today to speak to the international Space Station TV broadcasters send microwaves into space, the signals are received by geostationary satellites to beam the programmes down to Earth to cover a whole country

Japanese cooking required reheating, and since most Japanese houses and kitchens were small, microwave ovens were the perfect space savers. Japan exported microwaves to the United States in the 1970s
