5. we know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. how does it help us find out the make - up of stars?

Answer

Brief Explanations:

Each element in a star emits or absorbs light at specific wavelengths. By analyzing the electromagnetic - spectrum of starlight, we can identify the unique spectral lines of different elements present in the star, thus determining its chemical composition.
