Question

ch. 4 quiz 2
which instrument would be most useful for identifying the chemical composition of a star?
o telescope with infrared filter
o spectroscope
o microscope
o seismograph

Explanation:

A spectroscope is used to analyze the light from a star. By splitting the light into its component wavelengths (a spectrum), it reveals absorption or emission lines that correspond to specific chemical elements. This allows astronomers to determine the star's chemical composition. A seismograph measures seismic waves (earthquakes), a microscope is for small - scale objects (not stars), and a telescope with an infrared filter is more about detecting infrared radiation (e.g., heat signatures, not chemical composition directly).

Answer:

Spectroscope
