ASTRO 7N EXAM 2 2026 FULL QUESTIONS
AND CORRECT ANSWERS GRADED A+
◉ The spectrum of an oxygen lamp looks different than the spectrum of
a sodium lamp because: Answer: each atom has a unique set of electron
orbits
◉ What is the relationship between wavelength and frequency? Answer:
If frequency increases, the wavelength decreases.
◉ Even the largest ground-based telescopes have resolution restrictions
imposed by: Answer: atmospheric blurring of images
◉ Dark lines in the absorption spectrum represent: Answer: particular
energies of light coming in from a distant object that are absorbed by
material in between.
◉ Compare frequency of x-ray versus regular light. Answer: X-ray has a
larger frequency than visible light.
◉ When you magnify an object with a telescope, what else happens to
your view of the sky? Answer: Your field of view gets smaller, so you
can only see a small area of sky.
