Aradio telescope is used to study radio waves that come from stars and galaxies. what type of wave is a radio wave?
this is urgent ㋛

A radio wave is an electromagnetic wave.

Explanation:

A radio wave is an electromagnetic wave that is commonly used in information dissemination such as radio, television sets, etc.

They collect the radio waves, convert them to an electromagnetic spectrum which in turn converts them to sound waves.

Radio waves used to study galaxies are electromagnetic in nature.

Because radio waves have the longest wavelengths which can vary between 0.05 inches to 60 miles and because they have the lowest frequency, they are ideal for studying radio waves that comes from stars and galaxies

Electromagnetic wave is the correct answer.

Explanation:

the answer is prolly b

in the united states, the president is controlled by the

constitution, and in all respects subordinate to it. insofar

as it deals with presidential power, however, the american

constitution has proved to be a highly malleable document.

perhaps the framers of the american constitution feared

legislative power most of all; 2 but from well-known events

in the twentieth century, it is possible to conclude that it is

presidential power that holds out the greatest risks to both

liberty and democracy. the president is by far the most visible leader in the nation; he is often the only person in government with a national constituency. moreover, he is
