How does the electromagnetic spectrum relate to a grouping of stars based on color?
2 answers:
- From different wavelengths we can create a electromagnetic spectrum .
- From spectral lines of that electromagnetic spectrum astronomers can determine the element in the farther universe (star).
- They can also determine the temperature and density of that element in the star.
- The spectral lines in the electromagnetic spectrum tell us about any magnetic field of the star.
A useful formula of wavelength:
- wavelength is the length 7 of wave having SI unit lambda

Answer:
The correct representation is attached with the explanation.
Explanation:
In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
