Different chemical elements emit (or absorb) certain specific frequencies of light. When the light from a star is split in to it's rainbow spectrum of light, certain parts of the spectrum will be black (in absorption spectra) or brighter (in emission spectra). By comparing these lines to the known emission and absorption spectra of elements, the composition of a stars atmosphere can be determined.
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
Scientists use equipment so that they can figure out different substances in different objects which have not or have been tested
Scientists inferred that the Earth is made of layers through the study of seismic waves generated by earthquakes. By analyzing how these waves travel through the Earth, scientists were able to identify different layers based on variations in density, composition, and rigidity. This led to the development of the Earth's layered structure known as the crust, mantle, outer core, and inner core.
The identity transformation.
We study bacteria so that we can figure how fast they grow in different environments and temperatures and the different changes that the enzymes and proteins go through to be resistant to certain medication. . This helps scientists that study bacteria to figure out how to prevent that disease.
Scientists are trying to figure something out.
By knowing the SI units of length,mass,liquid,and other SI units helps them figure out stuffs
Scientists are trying to figure out
by digging holes in the earth
to help scientists figure things out.
Since composition is the organization of a piece of art, you can start by looking at how some drawings you like are organized. There will be patterns, try and figure out which drawings have the same horizon line, which have the same point of symmetry or vanishing point. Now for your composition, imagine a piece that combines traits from the composition of a few different pieces, or changes them up completely.
