The electromagnetic spectrum includes a continuous spectrum of wavelengths that include:
Radio waves, microwaves, infrared light, visible, ultraviolet, X-rays, gamma rays
The wavelength decreases from radio waves to gamma rays, whereas the energy increases along the same direction.
In the given example, radio waves have a lower energy and higher wavelength than visible light. The latter can be perceived by the human eye, whereas radio waves are not visible to the human eye.
1) They have colors = visible light
2) They can travel in a vacuum = both
3) They have energy = both
4) They’re used to learn about dust and gas clouds = radio waves
5) They’re used to find the temperature of stars = visible light
6)They’re invisible = radio waves
It's a quantitative observation because it includes numerical data.
Answer:
to have an accurate measure
Explanation:
Answer: A method of classifying stars by their temperatures and compositions.
Explanation:
I think trace 1 is ac and trace 2 if dc but i’m not sure what will happen when a higher frequency is added?
