Question

Explain how electromagnetic radiation helps scientists study the universe.

Answer 1

All stars have their own EM radiation, which makes their EM spectrum and from that scientist can know if star is approaching us or going away from us by "Blue shift" and "Red Shift" respectively. By this spectrum, they also can find out anything about star like it's heat, light, temperature etc.

Hope this helps!

Answer 2

The answer is: Electromagnetic radiation helps scientists to study the universe through detectors and the cosmic microwave background.

Step-by-step explanation:

The most important electromagnetic radiation is the one that comes from the Sun. It is the one that we can measure more accurately. It is very important to have detectors to be able to deepen the knowledge of the Sun and the surrounding atmosphere and how they influence the environment in which they are immersed.

Within the electromagnetic radiation is the "Cosmic microwave background", a background of light in the spectrum from which it comes from all directions, has a very low energy, has no impact on everyday life. Today it is known that it is a reflection of how the Universe was born, what happened after the Big Bang, which started in a very hot spot and expanded very quickly, gradually cooling.

The answer is: Electromagnetic radiation helps scientists to study the universe through detectors and the cosmic microwave background.
