Answer 1

Correct answers: A, C, D

- A: True — spectroscope and spectrometer are often used interchangeably (spectrometer emphasizes measurement).
- C: True — it splits light into its component colors (spectrum), like a prism or diffraction grating.
- D: True — spectroscopy reveals composition, temperature, velocity, etc., of astronomical objects.

B and E are false: B describes a stethoscope; E is incorrect — a spectroscope is not a telescope (though it can be attached to one).
