Submillimeter astronomy is a lecture and an article from the astronomy department for the course on the principles of radiation astronomy.

You are free to take this quiz based on submillimeter astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the course template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

TRUE
FALSE

14. The reason in principle that your automobile is not detecting submillimeter rays is

TRUE
FALSE

a rapid rise in temperature
not practical to prevent cosmic-ray events
understanding their behavior
deglitching
operating in a relatively high cosmic-ray flux

20. True or False, Radio observations taken by the Bernese Multibeam Radiometer for KOSMA (BEMRAK) at submillimeter wavelengths show an impulsive component that starts simultaneously with high-energy proton acceleration and the production of pions.

TRUE
FALSE

21. High-energy particle acceleration during an energetic solar flare may involve which of the following at submillimeter wavelengths:

a rapid rise in temperature
a gradual, long-lasting component
large apparent source sizes
synchrotron emission
a magnetic field strength of ≥ 200 Gauss
a close correlation in time and space of radio emission with pion production

Research

Hypothesis:

  1. Submillimeter radiation can differentiate chemical species.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
