travels in waves through space

Explanation:

A cosmic microwave background radiation is classified as a form of electromagnetic energy because it

travels in waves through space

The cosmic microwave background is assumed to be a left over radiation  from the Big Bang, or the time  when the universe began. This means its radiationis most visible in the microwave part of the electromagnetic spectrum.

The answer is:

Because it travels in waves through space.

Explanation:

CMB is a form of radiation discovered in 1965 that is presented as one of the main tests of the cosmic model since it is a type of radiation that fills the entire universe.

It has the characteristics of black-body radiation (a theoretical or ideal object that absorbs all light and all radiant energy incident on it) at a temperature of 2,725 K, with a frequency of 160.2 GHz and a length of 1.9mm wave belonging to the microwave. rank

i would say the answer is food.

hope this !

double the distance = divide strength by 4
