Answer:
By observing galaxies in multiple wavelengths of light, astronomers can uncover diverse temperature components and detect structures obscured by interstellar dust, gaining a more complete picture of the universe. The closest multiple-choice option is (c) To study different temperature components.
Step-by-step explanation:
Observing galaxies in multiple wavelengths allows astronomers to gather comprehensive data that is unavailable if only visible light is considered. In astronomy, different wavelengths can reveal varied physical conditions, such as different temperature components or structures obscured by interstellar dust.
For instance, infrared observations help us see through dust and observe more distant stars, while ultraviolet, X-ray, and gamma ray observations, which must be conducted from space due to Earth's atmospheric blocking, can shed light on high-energy processes and the galaxy's center. This multi-wavelength approach is crucial for a more complete understanding of the universe and aids scientists by acting as a suite of tools, each wavelength providing its own unique information, like revealing different layers or aspects of galactic phenomena.
