What is the primary purpose of astronomical spectroscopy?
Explanation: The primary purpose of astronomical spectroscopy is to analyze the composition and physical properties of celestial objects by studying the distribution of their light or electromagnetic radiation across different wavelengths.
What is the function of a spectrograph in astronomical observations?
Explanation: A spectrograph is an instrument used in astronomical observations to disperse light from celestial objects into its component wavelengths. It allows astronomers to analyze the spectrum of light and obtain information about the object's composition, temperature, and other physical properties.
What is the primary advantage of astronomical imaging over spectroscopy?
Explanation: The primary advantage of astronomical imaging over spectroscopy is that imaging provides more detailed information about celestial objects. It allows astronomers to capture and study the morphology, structure, and spatial distribution of objects, revealing intricate details that spectroscopy alone may not capture.
What is the purpose of using filters in astronomical imaging?
Explanation: Filters are used in astronomical imaging to enhance specific features or wavelengths in the image. They selectively transmit certain wavelengths of light while blocking others, allowing astronomers to isolate and study specific phenomena or objects of interest.
What is the primary advantage of using adaptive optics in astronomical imaging?
Explanation: The primary advantage of using adaptive optics in astronomical imaging is that it allows for higher spatial resolution in ground-based observations. By continuously measuring and correcting for atmospheric turbulence, adaptive optics systems can compensate for the blurring effect of the atmosphere and produce sharper and more detailed images.
