How do scientists use a spectroscope to determine a star's composition? A. They study patterns in light bands that are separated
from starlight by the spectroscope. B. They use the spectroscope to study sound waves that are traveling from the star. C. They use the spectroscope to create a man-made star that they study in a lab. D. They run tests on gas samples that the spectroscope collects from the star's core.
Answer: They study patterns in light bands that are separated from starlight by the spectroscope.
Step-by-step explanation: Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
