Astro 7n Unit 1 & 2 Quiz Answers (Exam
1)
From Earth, in which constellation might you find the planet Saturn? - correct answer-Taurus
Why don't we see the constellation Orion at night all throughout the year - correct answer-As
the Earth orbits the Sun, its nighttime side point to different constellations at different points
along its orbit
When is the best time for you to be able to see the constellation that is your sign of the
Zodiac? - correct answer-At midnight six months after your birthday
Constellations close to the North pole of Earth: - correct answer-Move in a circle around the
North star, Polaris, over the course of a single night.
There are a total of 88 constellations. Roughly how many of these can be seen at any given
time from a single location on a clear night? - correct answer-44
What is the relationship between wavelength and frequency? - correct answer-If the
frequency increases the wavelength decreases
Compare the frequency of an X-ray with that of visible light. - correct answer-The X-ray has
a larger frequency than visible light
Compare the frequency and wavelength of gamma ray with visible light. - correct
answer-Gamma ray frequency is higher and it's wavelength is lower
If the frequency of radiation is twice as large then its wavelength is... - correct answer-half as
large
The spectrum of an oxygen lamp looks different than the spectrum of a sodium lamp
because: - correct answer-each atom has a unique set of electron orbits
Dark lines in an absorption spectrum represent: - correct answer-particular energies of light
coming from a distant object that are absorbed by material in between
Which of the following is FALSE? - correct answer-The energy of a photon increases in
proportion to the wavelength of the radiation.
Which of the following is true? - correct answer-An absorption spectrum appears as
continuous spectrum interrupted by a series dark lines.
The electrons in a cloud of hydrogen gas are making the transition from excited states to the
ground state. What does the spectrum of this cloud of hydrogen gas look like? - correct
answer-It will consist of a few bright emission lines at specific wavelengths.
